Abstract The Kuramoto model is a mathematical model for describing the collective synchronization phenomena of coupled oscillators. We theoretically demonstrate that an array of coupled photonic crystal lasers emulates the Kuramoto model with non-del

Recently, coherent control of absorption in metallic metasurfaces has been demonstrated, and this phenomenon was applied to intriguing light-by-light switching operation. Here we experimentally demonstrate coherent control of beam deflection by hi

Nonlinear optical gates are usually considered as fundamental building blocks for universal optical computation. However, the performance is severely limited by small optical nonlinearity, thereby bounding their operation speed, consumption energy, a

We reveal imaginary coupling components in the coupled-mode theory for evanescently coupled cavities with gain and loss. We show how exceptional points are resolved and restored in such systems where their effects are generally inevitable.

In this talk, we theoretically and experimentally investigate intriguing optical properties of non-Hermitian coupled nanoresonators based on two dimensional photonic crystals. Firstly, we demonstrate that a one dimensional array of PT symmetric coupl

We experimentally demonstrate the first exceptional point transition of two electrically pumped photonic crystal lasers. Clear spectral coalescence and enhancement by the process are observed via high-Q nanocavities with controlled current injection.

Topological photonics has emerged as a novel route to engineer the flow of light. Topologically-protected photonic edge modes, which are supported at the perimeters of topologically-nontrivial insulating bulk structures, have been of particular inter
