摘要
An optically pumped mid-infrared vertical-cavity surface-emitting laser based on an active region with a "W" configuration of type-II antimonide quantum wells is reported. The emission wavelength of 2.9 mu m has a weak temperature variation (d lambda/dT approximate to 0.07 -0.09 nm/K), and the multimode linewidth is quite narrow (2.5-4 nm). Lasing is observed up to T = 280 K in pulsed mode and up to 160 K cw. Under cw excitation at T = 78 ii, the threshold pump power is as low as 4 mW for a 6 mu m spot, and the differential power conversion efficiency is 4.5%.
