摘要：

We present second-harmonic surface emission from distributed feedback GaAs/AlGaAs quantum-cascade lasers with integrated intersubband nonlinearities. The devices show single mode fundamental and second-harmonic emission at wavelengths of 10.7 and 5.35 mu m, respectively. Only 5.35 mu m light is emitted from the surface, as the fundamental light is not coupling to radiating modes for the grating of our choice. The second-harmonic peak optical power via the surface at 78 K is 150 mu W for a fundamental peak power of 1.1 W.
