Strong coupling between a single quantum dot and an L4/3 photonic crystal nanocavity
Kazuhiro Kuruma, Yasutomo Ota, Masahiro Kakuda +2
We demonstrate strong coupling between a single quantum dot and a GaAs-based L4/3-type photonic crystal nanocavity. The L4/3 cavity supports a high theoretical Q factor (~8{\times}…
Microcavity-based Generation of Full Poincaré Beams with Arbitrary Skyrmion Numbers
Wenbo Lin, Yasutomo Ota, Yasuhiko Arakawa +1
A full Poincaré (FP) beam possesses all possible optical spin states in its cross-section, which constitutes an optical analogue of a skyrmion. Until now, FP beams have been exclus…
Surface-passivated high-Q GaAs photonic crystal nanocavity with quantum dots
Kazuhiro Kuruma, Yasutomo Ota, Masahiro Kakuda +2
Photonic crystal (PhC) nanocavities with high quality (Q) factors have attracted much attention because of their strong spatial and temporal light confinement capability. The resul…
