Zero-cell photonic crystal nanocavity laser with quantum dot gain
Masahiro Nomura, Yasutomo Ota, Naoto Kumagai +2
We demonstrate laser oscillation in a hexagonal-lattice photonic crystal nanocavity using an InGaAs quantum dot gain material by optical pumping at 5 K. The cavity comprises a defe…
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…
Photonic crystal nanocavity laser with a single quantum dot gain
Masahiro Nomura, Naoto Kumagai, Satoshi Iwamoto +2
We demonstrate a photonic crystal nanocavity laser essentially driven by a self-assembled InAs/GaAs single quantum dot gain. The investigated nanocavities contain only 0.4 quantum…
Laser oscillation in a strongly coupled single quantum dot-nanocavity system
M. Nomura, N. Kumagai, S. Iwamoto +2
Strong coupling of photons and materials in semiconductor nanocavity systems has been investigated because of its potentials in quantum information processing and related applicati…
