Widely tunable mid-infrared quantum cascade lasers using sampled grating reflectors

Opt Express. 2012 Oct 8;20(21):23339-48. doi: 10.1364/OE.20.023339.

Abstract

We demonstrate a three-section, electrically pulsed quantum cascade laser which consists of a Fabry-Pérot section placed between two sampled grating distributed Bragg reflectors. The device is current-tuned between ten single modes spanning a range of 0.46 μm (63 cm(-1)), from 8.32 to 8.78 μm. The peak optical output power exceeds 280 mW for nine of the modes.
