Different techniques for processing InP-based lambda =9 mu m quantum cascade lasers which improve the thermal dissipation in the device are presented. Lasers with a thick electroplated gold layer show CW operation up to 278 K and 1 W of optical power at 280 K in pulsed operation and with such a process, the thermal characteristics of the lasers are improved with an output average power of 174 mW at a duty cycle of 40% measured at 10 degree centigrade for 2-mm-long laser.
