Abstract
We report on the observation of photorefractivity in vanadium‐doped zinc telluride in the 0.63–1.3‐μm‐wavelength range. Photorefractive two‐beam coupling, along with photoluminescence and absorption spectroscopy, are used to characterize a vapor‐phase transfer‐grown crystal. At 0.63 μm, we measure a grating‐formation time of 15 μs at an intensity of 4.7 W/cm2, which is comparable to GaAs at 1.06 μm, and is faster than photorefractive cubic and ferroelectric oxides.Keywords
