Abstract

The authors exptl. demonstrate surface-emitting 2nd harmonic generation in a waveguide contg. asym. coupled GaAs/AlGaAs quantum wells. The nonlinear conversion efficiency is enhanced by reversing the asym. well orientation every coherence length, to quasiphase match the vertical 2nd harmonic generation process. The measured spectrum of the asym. quantum well susceptibility is dominated by an excitonic peak at a pump frequency corresponding to half of the 1st electron-heavy hole transition energy.
