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…
