GaP: a new photorefractive material

Abstract

The photorefractive effect is a handy nonlinear optical effect for low and moderate power cw lasers and can be used in optical image processing. Most ferroelectric or paraelectric materials have photorefractive sensitivity in the middle region of the visible spectrum, whereas semiconductors have it in the IR. We describe the photorefractive effect of semi-insulating undoped GaP,1 which is sensitive in the 0.6-0.9-μm spectral region because of its relatively large band gap of 2.26 eV. Therefore, this material fills the spectral gap between dielectric materials and semiconductors (GaAs and InP), to which the spectra of GaAlAs laser diodes belong.
