Topological multiband photonic superlattices
Bikashkali Midya, Liang Feng
A one-dimensional discrete lattice of dimers is known to possess topologically protected edge states when interdimer coupling is stronger than intradimer coupling. Here, we address…
Supercharge optical arrays
Bikashkali Midya, Wiktor Walasik, Natalia M. Litchinitser +1
We introduce the notion of a supercharge optical array synthesized according to supersymmetric charge operators. Starting from an arbitrary array, mathematical supersymmetry transf…
Supersymmetry-guided method for mode selection and optimization in coupled systems
Wiktor Walasik, Bikashkali Midya, Liang Feng +1
Single-mode operation of coupled systems such as optical-fiber bundles, lattices of photonic waveguides, or laser arrays requires an efficient method to suppress unwanted super-mod…
