Efficient light couplers to topological slow light waveguides in valley photonic crystals
Hironobu Yoshimi, Takuto Yamaguchi, Satomi Ishida +2
We numerically and experimentally demonstrate efficient light couplers between topological slow light waveguides in valley photonic crystals (VPhCs) and wire waveguides. By numeric…
High-Q two-dimensional photonic crystal nanocavity on glass with an upper glass thin film
Ryusei Kawata, Akinari Fujita, Natthajuks Pholsen +2
We numerically analyze two-dimensional photonic crystal (PhC) nanocavities on glass with a thin glass film on top of the structure. We investigated a multi-step heterostructure GaA…
Nonadiabatic nonlinear non-Hermitian quantized pumping
Motohiko Ezawa, Natsuko Ishida, Yasutomo Ota +1
We analyze a quantized pumping in a nonlinear non-Hermitian photonic system with nonadiabatic driving. The photonic system is made of a waveguide array, where the distances between…
