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…
Experimental demonstration of topological slow light waveguides in valley photonic crystals
Hironobu Yoshimi, Takuto Yamaguchi, Ryota Katsumi +3
We experimentally demonstrate topological slow light waveguides in valley photonic crystals (VPhCs). We employed a bearded interface formed between two topologically-distinct VPhCs…
In-situ wavelength tuning of quantum-dot single-photon sources integrated on a CMOS silicon chip
Ryota Katsumi, Yasutomo Ota, Alto Osada +6
Silicon quantum photonics provides a promising pathway to realize large-scale quantum photonic integrated circuits (QPICs) by exploiting the power of complementary-metal-oxide-semi…
GaAs valley photonic crystal waveguide with light-emitting InAs quantum dots
Takuto Yamaguchi, Yasutomo Ota, Ryota Katsumi +5
We report a valley photonic crystal (VPhC) waveguide in a GaAs slab with InAs quantum dots (QDs) as an internal light source exploited for experimental characterization of the wave…
Quantum-dot single-photon source on a CMOS silicon photonic chip integrated using transfer printing
Ryota Katsumi, Yasutomo Ota, Alto Osada +6
Silicon photonics is a powerful platform for implementing large-scale photonic integrated circuits (PICs), because of its compatibility with mature complementary-metal-oxide-semico…
