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…
