Low-Threshold Ultrafast Surface-Passivated Photonic Crystal Nanocavity Lasers
2007
Lasers and Electro-Optics Society Annual Meeting (LEOS), IEEE
Efficiency and speed of photonic crystal lasers are improved by passivating InGaAs/GaAs membranes using (NH 4 )S treatment. Lasers show five-fold reduction in nonradiative surface recombination rate, resulting in four-fold reduction in threshold and room-temperature operation with near THz response.
