Abstract
We provide a feasible and compact scheme to control and stabilize the spatiotemporal dynamics of broad-area semiconductor (BAS) lasers. The proposal is based on the ability of non-Hermitian potentials with given local symmetries to manage the flow of light. A local PT-symmetric configuration allows controlling, enhancing, and localizing the generated light. We impose a pump modulation, with a central symmetry axis which induces in-phase gain and refractive index modulations due to the Henry fact...
