Abstract
Recent experiments in mid-IR frequency conversion reveal that older Sellmei er models for zinc germanium phosphide are inadequate for predicting phase- matching loci in zinc germanium phosphide optical frequency-conversion devi ces. This results in compromised device performance. We conduct a complete study of the refractive indices of zinc germanium phosphide from 2 to 9 mum and calculate new Sellmeier coefficients. The phase-matching calculations based an our new refractive-index data predict much more closely the result s of several different mid-IR frequency-conversion experiments.
