Temperature Dependence of Optical Gain and Loss in 8.2a10.2 m Quantum-Cascade Lasers

Temperature-dependent optical gain and waveguide loss have been measured for continuous-wave operated quantum-cascade lasers with wavelengths between 8.2 and 10.2 mum up to room temperature using the Hakki-Paoli method. The gain coefficient decreases with increasing temperature, and is close to the...
