Abstract :
A report is presented on the continuous-wave operation of λ≃5 μm GaInAs/AlInAs/InP-based quantum cascade lasers up to a heatsink temperature of 222 K (-51°C). The devices are mounted epi-side down with high-reflection coated facets. The dissipated electrical power at threshold amounts to only 2.3 W at 222 K.
