We observe room-temperature intracavity difference-frequency generation in the mid-infrared range in a butt-joint GaAs/InGaAs/InGaP quantum-well laser diode which supports lasing at two closely spaced wavelengths in the near-infrared range around 1 [mu]m. We employ a special asymmetric waveguide de ... [Appl. Phys. Lett. 92, 021122 (2008)] published Thu Jan 17, 2008.
