A spectrum for the electro-optic coefficient of cadmium telluride measured from 3 to 14 pLm is reported. The spectrum shows that the quantity n3r 4l has a nearly constant value of 1.09 × 10-10 m/V over this spectral band, with a slight (5%) dip at the weak absorption band centered at 6 tim. Measurements were performed with an infrared Mueller matrix spectropolarimeter. Transmission spectra of the Mueller matrix were acquired at a set of applied voltages. Retardance spectra were calculated from Mueller matrix spectra, and then the electro-optic coefficient was calculated at each wavelength by a least-squares fit to the resulting retardance as a function of voltage.
