Photonic Crystal Defect Nanocavities Based on Monocrystalline Yttrium Iron Garnet
Kota Taniguchi, Siyuan Gao, Tatsuya Kitai +5
Monocrystalline yttrium iron garnet (YIG) is a key material for magneto optics and quantum magnonics owing to its high optical transparency, large magneto-optical (MO) effects at r…
Quantum dot single photon source on SiN integrated with coupled crossover waveguides
Akinari Fujita, Hironobu Yoshimi, Natthajuks Pholsen +5
Hybrid integration of InAs/GaAs quantum dot (QD) single-photon sources (SPSs) is a promising approach for introducing quantum light into SiN photonic integrated circuits. However,…
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…
Topologically-protected single-photon sources with topological slow light photonic crystal waveguides
