Paper Abstract

The high power operation of mid-infrared quantum cascade lasers at temperatures up to T equals 320 K is reported. Gain at high temperature is optimized by a design combining low doping, a funnel injector and a three well vertical transition active region. A molecular beam epitaxy grown InP top cladding layer is also used to optimize heat dissipation. Peak pulsed optical power of 200 mW and average power of 6 mW are obtained at 300 K and at a wavelength (lambda) equals 5.2 micrometers . At (lambda) equals 8.5 micrometers , the pulsed optical power is 10 mW.
