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…

Valley photonic crystal waveguides fabricated with CMOS-compatible process
Takuto Yamaguchi, Hironobu Yoshimi, Miyoshi Seki +5
Valley photonic crystal (VPhC) waveguides have attracted much attention because of their ability to enable robust light propagation against sharp bends. However, their demonstratio…
