AbstractAn 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 ym has a weak temperature variation (dλ/dT ≈ 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 K, the threshold pump power is as low as 4 mW for a 6 am spot, and the differential power conversion efficiency is 4.5%.
