AB  - The THz beamline at FLASH, DESY, provides both tunable (1–300 THz) narrow-bandwidth (∼10%) and broad-bandwidth intense (up to 150 uJ) THz pulses delivered in 1 MHz bursts and naturally synchronized with free-electron laser X-ray pulses. Combination of these pulses, along with the auxiliary NIR and VIS ultrashort lasers, supports a plethora of dynamic investigations in physics, material science and biology. The unique features of the FLASH THz pulses and the accelerator source, however, bring along a set of challenges in the diagnostics of their key parameters: pulse energy, spectral, temporal and spatial profiles. Here, these challenges are discussed and the pulse diagnostic tools developed at FLASH are presented. In particular, a radiometric power measurement is presented that enables the derivation of the average pulse energy within a pulse burst across the spectral range, jitter-corrected electro-optical sampling for the full spectro-temporal pulse characterization, spatial beam profiling along the beam transport line and at the sample, and a lamellar grating based Fourier transform infrared spectrometer for the on-line assessment of the average THz pulse spectra. Corresponding measurement results provide a comprehensive insight into the THz beamline capabilities.

AB  - Ultrafast-laser inscribed optical memories have been considered as a high-density low-energy-consumption alternative to the magnetization-based memories. The optical memories are based on laser-induced material modifications resulting in the refractive index change. The long-term stability of such modifications has been indicated by subjecting them to the accelerated aging by annealing at elevated temperatures. Here, the first direct evidence is provided of the durability of the type II refractive index change in BK7 glass. The investigation was performed for over 27 months at room temperature. The results show the existence of the laser pulse intensity threshold above which the magnitude of the index change does not deteriorate with time and, hence, is suitable for optical memory, photonic crystal and fibre-grating writing. © 2019

AB  - Objective: The ventilators involved in non-invasive mechanical ventilation commonly provide ventilator support via a facemask. The interface of the mask with a patient promotes air leaks that cause errors in the feedback information provided by a pneumatic sensor and hence patient-ventilator asynchrony with multiple negative consequences. Our objective is to test the possibility of using chest-wall motion measured by an optical fibre-grating sensor as a more accurate non-invasive ventilator triggering mechanism. Approach: The basic premise of our approach is that the measurement accuracy can be improved by using a triggering signal that precedes pneumatic triggering in the neuro-ventilatory coupling sequence. We propose a technique that uses the measurement of chest-wall curvature by a long-period fibre-grating sensor. The sensor was applied externally to the rib-cage and interrogated in the lateral (edge) filtering scheme. The study was performed on 34 healthy volunteers. Statistical data analysis of the time lag between the fibregrating sensor and the reference pneumotachograph was preceded by the removal of the unwanted heartbeat signal by wavelet transform processing. Main results: The results show a consistent fibregrating signal advance with respect to the standard pneumatic signal by (230 +/- 100) ms in both the inspiratory and expiratory phases. We further show that heart activity removal yields a tremendous improvement in sensor accuracy by reducing it from 60 ml to 0.3 ml. Significance: The results indicate that the proposed measurement technique may lead to a more reliable triggering decision. Its imperviousness to air leaks, non-invasiveness, low-cost and ease of implementation offer good prospects for applications in both clinical and homecare ventilation.

AB  - The faithful state transfer is an important requirement in the construction of classical and quantum computers. While the highspeed transfer is realized by optical-fibre interconnects, its implementation in integrated optical circuits is affected by cross-talk. The cross-talk between densely packed optical waveguides limits the transfer fidelity and distorts the signal in each channel, thus severely impeding the parallel transfer of states such as classical registers, multiple qubits and qudits. Here, we leverage on the suitably engineered cross-talk between waveguides to achieve the parallel transfer on optical chip. Waveguide coupling coefficients are designed to yield commensurate eigenvalues of the array and hence, periodic revivals of the input state. While, in general, polynomially complex, the inverse eigenvalue problem permits analytic solutions for small number of waveguides. We present exact solutions for arrays of up to nine waveguides and use them to design realistic buses for multi-(qu)bit and qudit transfer. Advantages and limitations of the proposed solution are discussed in the context of available fabrication techniques.

AB  - Određivanje prisustva neutrona tokom niskofonskih gama spektrometrijskih merenja je
od posebne važnosti. Zbog toga je u ovom radu analiziran način određivanja
energetskog spektra neutrona prisutnog u merenjima sa HPGe detektorima. Ovaj metod
se zasniva na korišćenju metoda dekonvolucije. Za to je neophodno poznavati gama
aktivnost indukovanu neutronskim reakcijama sa različitim izotopima germanijuma kao
i efikasne preseke za date neutronske reakcije. Ovaj pristup je testiran merenjima sa
fisionim izvorom neutrona 252Cf koji je bio postavljen u blizini HPGe detektora.
Dobijeni rezultati pokazuju da ovaj metod moze pružiti pouzdane podatke o obliku
energetskog spektra neutrona tokom gama spektrometrijskih merenja.
AB  - Determination of neutron spectra in the Ge-detector during low-level gamma
spectroscopy measurements is of great importance. Thus, in this paper we analyzed the
method for the determination of neutron energy spectra present during measurements
with HPGe detectors. This method is based on using the deconvolution procedure. It
requires the knowledge of neutron induced gamma activities of Ge isotopes and the
cross section data for the neutron reactions of interest. This approach was tested with
measurements that used the fission neutron source 252Cf placed in proximity of the
HPGe detector. Results show that this method can provide reliable data about the shape
of neutron energy spectrum during gamma spectroscopy measurements.

abstract = "Određivanje prisustva neutrona tokom niskofonskih gama spektrometrijskih merenja je
od posebne važnosti. Zbog toga je u ovom radu analiziran način određivanja
energetskog spektra neutrona prisutnog u merenjima sa HPGe detektorima. Ovaj metod
se zasniva na korišćenju metoda dekonvolucije. Za to je neophodno poznavati gama
aktivnost indukovanu neutronskim reakcijama sa različitim izotopima germanijuma kao
i efikasne preseke za date neutronske reakcije. Ovaj pristup je testiran merenjima sa
fisionim izvorom neutrona 252Cf koji je bio postavljen u blizini HPGe detektora.
Dobijeni rezultati pokazuju da ovaj metod moze pružiti pouzdane podatke o obliku
energetskog spektra neutrona tokom gama spektrometrijskih merenja., Determination of neutron spectra in the Ge-detector during low-level gamma
spectroscopy measurements is of great importance. Thus, in this paper we analyzed the
method for the determination of neutron energy spectra present during measurements
with HPGe detectors. This method is based on using the deconvolution procedure. It
requires the knowledge of neutron induced gamma activities of Ge isotopes and the
cross section data for the neutron reactions of interest. This approach was tested with
measurements that used the fission neutron source 252Cf placed in proximity of the
HPGe detector. Results show that this method can provide reliable data about the shape
of neutron energy spectrum during gamma spectroscopy measurements.",

AB  - We address the stability and dynamics of eigenmodes in linearly shaped strings (dimers, trimers, tetramers, and pentamers) built of droplets in a binary Bose-Einstein condensate (BEC). The binary BEC is composed of atoms in two pseudo-spin states with attractive interactions, dressed by properly arranged laser fields, which induce the (pseudo-) spin-orbit (SO) coupling. We demonstrate that the SO-coupling terms help to create eigenmodes of particular types in the strings. Dimer, trimer, and pentamer eigenmodes of the linear system, which correspond to the zero eigenvalue (EV, alias chemical potential) extend into the nonlinear ones, keeping an exact analytical form, while tetramers do not admit such a continuation, because the respective spectrum does not contain a zero EV. Stability areas of these modes shrink with the increasing nonlinearity. Besides these modes, other types of nonlinear states, which are produced by the continuation of their linear counterparts corresponding to some nonzero EVs, are found in a numerical form (including ones for the tetramer system). They are stable in nearly entire existence regions in trimer and pentamer systems, but only in a very small area for the tetramers. Similar results are also obtained, but not displayed in detail, for hexa-and septamers. Published by AIP Publishing.

AB  - The ventilators involved in mechanical ventilation are usually equipped with pneumatic sensor detecting patients own respiratory effort in order to assist spontaneous breathing. However, the interface of the mask with the patient promotes air leaks that affect the measurement of pneumatic variables and hence induces patient-ventilator asynchrony. In this paper we describe a new method and apparatus for continuous monitoring of the respiration based on the measurement of chest wall movements. The proposed solution uses a long-period fibre grating sensor attached to patients thorax and a simple and cost-effective monochromatic measurement scheme. On a set of healthy volunteers, we have established the linear correlation between the change in local torso curvature and the tidal volume during clinically relevant breathing patterns. The chest-wall movement measured by the grating advances with respect to the air-flow signal by about 200 ms, indicating the possibility to lead to more confidence triggering decision. The proposed scheme is non-invasive, simple, low-cost, and immune to air-leaks and drifts that are limiting factors in the currently standard pneumatic measurement techniques.

AB  - Non-invasive ventilation performed through an oronasal mask is a standard in clinical and homecare mechanical ventilation. Besides all its advantages, inevitable leaks through the mask cause errors in the feedback information provided by the airflow sensor and, hence, patient-ventilator asynchrony with multiple negative consequences. Here we investigate a new way to provide a trigger to the ventilator. The method is based on the measurement of rib cage movement at the onset of inspiration and during breathing by fibre-optic sensors. In a series of simultaneous measurements by a long-period fibre grating sensor and pneumotachograph we provide the statistical evidence of the 200 ms lag of the pneumo with respect the fibre-optic signal. The lag is registered consistently across three independent delay metrics. Further, we discuss exceptions from this trend and identify the needed improvements to the proposed fibre-sensing scheme.

The conditions of the existence and stability of coherent light propagation in multicore fibers with circularly arranged cores are derived. The multicore fiber is modeled by the linear discrete complex Ginzburg-Landau equation, while its eigenvalues are found analytically. The inverse eigenvalue problem proposing the commensurability of eigenvalues is solved to find the intercore coupling coefficients that support periodic revivals of the input state. Both planar modes and vortices are considered. Effects of the central core and material loss/gain on eigenvalue commensurability conditions and mode dynamics are studied in detail.

AB  - Here we present a comprehensive theoretical study of a porous-film sensor of fluid in Mach-Zehnder configuration. It is found that the penetration of a fluid into the film pores causes amplitude and phase modulation of the interferometer output signal, maximizing the sensitivity at a certain value of the fluid refractive index. We define the Fisher information for this interferometer and show that it is a good measure of its sensitivity, hence suitable as an evaluation function in sensor optimization. We propose the sensor structure and design thin films that maximize its sensitivity to water, alcohol solutions and oils. The estimated sensitivity of the order of 10(-5) RIU to the fluid refractive index and of 5 pm to the changes in the film thickness indicate the potential of this sensor for applications in biomedicine, chemistry and environmental protection, and as a tool for the film characterization.

AB  - In this Letter, a multiport directional optical coupler based on periodic energy exchange in a linear waveguide array is proposed. The periodic power transfer is achieved by choosing waveguide separations that render commensurate eigenvalues of the array coupling matrix. This is a general solution and offers a plethora of possibilities. Particularly interesting is an array that can be used to realize different couplers by simply choosing a different input waveguide. The proposed design principle is validated by full numerical simulations of realistic devices and the required fabrication precision is estimated. The proposed couplers are of interest for quantum optics, biosensing, and communications. (C) 2015 Optical Society of America

AB  - Atomic memories for flying photonic qubits are an essential ingredient for many applications like e.g. quantum repeaters. Verification of the coherent transfer of information from a light field to an atomic superposition is usually obtained using an optical read-out. In this paper we report the direct detection of the atomic coherence by means of atom interferometry. We experimentally verified both that a bichromatic laser field closing a Raman transition imprints a distinct, controllable phase on the atomic coherence and that it can be recovered after a variable time delay.

AB  - In non-invasive ventilation, continuous monitoring of respiratory volumes is essential. Here, we present a method for the measurement of respiratory volumes by a single fiber-grating sensor of bending and provide the proof-of-principle by applying a calibration-test measurement procedure on a set of 18 healthy volunteers. Results establish a linear correlation between a change in lung volume and the corresponding change in a local thorax curvature. They also show good sensor accuracy in measurements of tidal and minute respiratory volumes for different types of breathing. The proposed technique does not rely on the air flow through an oronasal mask or the observation of chest movement by a clinician, which distinguishes it from the current clinical practice.

We investigate the influence of sensor geometry and thin-film porosity on the attenuation of guided modes caused by their interaction with the gas. We show that film porosity is a critical parameter that should be carefully optimized for a chosen mode. These findings served as a basis for the design of an experimentally realizable sensor of carbon dioxide.

AB  - Mechanical physiological pulsations are movements of a body surface incited by the movements of muscles in organs inside the body. Here we demonstrate the use of long-period grating sensors in the detection of cardio-vascular pulsations (CVP), in particular apex and carotid pulsations. To calibrate the sensors, we use a mechanical tool designed specifically to measure the sensor response to a localized perturbation at different grating curvatures as working points. From the data we infer the amplitude of the CVP. Together with the electrophysiological signals, the CVP signals obtained from the sensors can provide significant information on heart function which is inaccessible to the electrocardiogram. The low cost and easy handling of the fibre sensors increase their prospects to become the sensors of choice for novel diagnostic devices.

AB  - Respiratory-volume monitoring is an indispensable part of mechanical ventilation. Here we present a new method of the respiratory-volume measurement based on a single fibre-optical long-period sensor of bending and the correlation between torso curvature and lung volume. Unlike the commonly used air-flow based measurement methods the proposed sensor is drift-free and immune to air-leaks. In the paper, we explain the working principle of sensors, a two-step calibration-test measurement procedure and present results that establish a linear correlation between the change in the local thorax curvature and the change of the lung volume. We also discuss the advantages and limitations of these sensors with respect to the current standards.

AB  - Matter-wave interferometry is a powerful tool for high-precision measurements of the quantum properties of atoms, many-body phenomena and gravity. The most precise matter-wave interferometers exploit the excellent localization in momentum space and coherence of the degenerate gases. Further enhancement of the sensitivity and reduction of complexity are crucial conditions for the success and widening of their applications. Here we introduce a multi-state interferometric scheme that offers advances in both these aspects. The coherent coupling between Bose-Einstein condensates in different Zeeman states is used to generate high-harmonic output signals with an enhanced resolution and the maximum possible interferometric visibility. We demonstrate the realization of such an interferometer as a compact, easy to use, atomchip device. This provides an alternative method for the measurement of the light-atom and surface-atom interactions and enables the application of multi-parameter sensing schemes in cold-atom interferometry.

AB  - We here present a model of nonlinear dynamics of microtubules (MT) in the context of modified extended tanh-function (METHF) method. We rely on the ferroelectric model of MTs published earlier by Sataric et al. [1] where the motion of MT subunits is reduced to a single longitudinal degree of freedom per dimer. It is shown that such nonlinear model can lead to existence of kink solitons moving along the MTs. An analytical solution of the basic equation, describing MT dynamics, was compared with the numerical one and a perfect agreement was demonstrated. It is now clearer how the values of the basic parameters of the model, proportional to viscosity and internal electric field, impact MT dynamics. Finally, we offer a possible scenario of how living cells utilize these kinks as signaling tools for regulation of cellular traffic as well as MT depolymerisation. (C) 2012 Elsevier Ltd.
