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…

Transfer-printed quantum-dot nanolasers on a silicon photonic circuit
A. Osada, Y. Ota, R. Katsumi +3
Quantum-dot (QD) nanolasers integrated on a silicon photonic circuit are demonstrated for the first time. QD nanolasers based on one-dimensional photonic crystal nanocavities conta…
