Abstract

We analytically describe quasi-phase matched second-harmonic generation in the mid-IR region in a parallel isotropic semiconductor slab made of Zinc Telluride (ZnTe) and Cadmium Telluride (CdTe) using total internal reflection quasi phase matching technique. The simulated results indicate conversion efficiencies of 4.08% (centered at 8.495 μm) and 15.83% (centered at 9.341 μm) in a 400 μm thick, 10-mm-long slab of ZnTe and CdTe respectively. The losses due to surface roughness, Goos-Hänchen shift and absorption of the slab have been considered in the analysis. The effect of variation in the angle of incidence has been studied for both the materials.
