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…
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…
Circularly-Polarized Light Emission from Semiconductor Planar Chiral Photonic Crystal
Kuniaki Konishi, Masahiro Nomura, Naoto Kumagai +3
We proposed and demonstrated a scheme of surface emitting circularly polarized light source by introducing strong imbalance between left- and right-circularly polarized vacuum fiel…
