Abstract
Quasi-phase-matched (QPM) GaAs structures, 0.5 mm thick, 10 mm long, and with grating periods, were grown by a combination of molecular-beam epitaxy and hydride vapor phase epitaxy. These were characterized by use of mid-IR second-harmonic generation (SHG) with a (ZGP) optical parametric oscillator as a pump source. The SHG efficiencies of QPM GaAs and QPM were directly compared, and a ratio of nonlinear coefficients was found at fundamental wavelength. For input pulse energies as low as and pulse duration, an internal SHG conversion efficiency of 33% was measured in QPM GaAs.
