2D and 3D photonic crystal nanocavity lasers with quantum dot gain

We discuss our recent results on 2D and 3D photonic crystal (PhC) nanocavity lasers. By utilizing high quality InAs quantum dots (QDs), we demonstrated various types of 2D PhC nanocavity lasers including a single dot laser. The micromanipulation technique boosts the quality factor of 3D PhC nanocavity, which facilitated the first demonstration of lasing oscillation in 3D PhC nanocavity. A silicon-based 3D PhC nanocavity laser with QD gain is also discussed.
