Photonic time crystals (PTCs), materials with a dielectric permittivity that is modulated periodically in time, offer new concepts in light manipulation. We study theoretically the emission of light from a radiation source placed inside a PTC and fin

Conference on Lasers and Electro-Optics.
We introduce topological phases in photonic space-time crystals, which have gaps in both momentum and frequency. We show that edge states waves refracted and reflected from spatial and temporal interfaces are governed by topological invariants.

We study light propagation in spatio-temporal photonic crystals: media whose electromagnetic properties vary periodically in both time and space. We find unique eigenmodes inside mixed energy-momentum gaps, extracting energy and momentum from the mod

We study the time reflection of evanescent fields beyond the critical angle of total internal reflection, caused by a sudden temporal change in permittivity. We find high sensitivity of the time-reflection near the critical angle.

Photonic time-crystals (PTCs) are spatially-homogeneous media whose electromagnetic (EM) susceptibility varies periodically in time, causing temporal reflections and refractions for any wave propagating within the medium. The time-reflected and time-

Topologically locked for emission The output power from a laser system can be increased by forming an array of lasers; however, because the individual lasers are independent, the resultant output may not be coherent. Dikopoltsev et al . report on the

Anderson localization is a fundamental wave phenomenon predicting that transport in a 1D uncorrelated disordered system comes to a complete halt, experiencing no transport whatsoever. However, in reality, a disordered physical system is always correl

We present the first experimental demonstration of a topological insulator VCSEL array. Our laser consists of 30 emitters, emitting in a single frequency, displaying interference proving that the emitters act as a single laser.
