Majorana bound state cavities

Cavities play a fundamental role in optical physics by providing spatiotemporal confinement of energy that facilitates light-matter interactions. They are routinely utilized variety settings, ranging from lasers to spectral filters, nonlinear wave mixers, and modulators. While their resonant properties make them suitable for sensing, many applications, like lasers, it is desired alleviate sensitivity order device more resilient perturbations. Along these lines there have been several recent reports using concepts topological design laser arrays inherently robust. Here, we present class cavities based on Majorana bound states provide unique scaling features as well nondegenerate single-mode behaviors. These may lead new family robust defects, fabrication imperfections, external
