Integration of diamond nanobeams with SnVs on Al2O3 waveguides for scalable quantum photonic chip application
Yeting Yang, Ryota Kitagawa, Tetsuya Miyatake +14
Tin vacancy (SnV) centers in diamond are promising solid state qubits for integrated quantum photonics. Here, we fabricate and characterize a diamond on Al2O3 dual taper waveguide…
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…
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…
Lasing oscillation in a three-dimensional photonic crystal nanocavity with a complete bandgap
Aniwat Tandaechanurat, Satomi Ishida, Denis Guimard +3
We demonstrate lasing oscillation in a three-dimensional photonic crystal nanocavity. The laser is realized by coupling a cavity mode, which is localized in a complete photonic ban…
Investigation of the spectral triplet in strongly coupled quantum dot-nanocavity system
Yasutomo Ota, Naoto Kumagai, Shunsuke Ohkouchi +6
We experimentally investigated the excitation power dependence of a strongly coupled quantum dot (QD)-photonic crystal nanocavity system by photoluminescence (PL) measurements. At…
