Impact of the vortex distortion phase on the efficiency of lasing zero-mode
Апстракт
Photonic lattices of optical waveguides present a well-controlled platform for investigation of different phenomena associated with the topological characteristics of physical systems. Recently, the first experimental realization of a Majorana zero-mode bound at vortexlike distortion induced in the bulk of a 2D graphene-like photonic lattice is demonstrated in [1]. The observed modes lie mid-gap at zero energy and they are extremely robust to the perturbations to the underlying Hamiltonian. We use bipartite armchair hexagonal lattice and create a vortex topological defect by perturbing positions of the central waveguides and numerically examine how the eigenvalues spectrum depends on the distortion phase. The observed robustness of zero-mode is an indication that adding the saturable gain and linear loss to lattice can lead to efficient lasing. Starting from the noisy background, we achieve zero-mode lasing, shown in Figure 1. We further investigate its robustness to the changes in dri...ving conditions and the vortex phase with the goal to find an efficeint and steady lasing regime. These results can be used to design a new topological laser.
