Abstract

We report on the experimental observation of very large self-deflection of optical beams, along with all-optical steering, and electro-optic beam deflection. We observe as many as 27 resolvable spots of deflection at 1-W/cm2 intensity. These deflections arise from enhanced photorefractive effects in CdZnTe:V, giving rise to optically induced index changes in excess of 0.08, which is to our knowledge the strongest nonlinearity ever reported for any bulk semiconductor.

Setup: A 900-nm beam is passed through a wave plate and a polarizer to control its intensity and polarization. The CZT crystal is illuminated uniformly by a 1527-nm beam and biased by a dc field applied through triangular parallel electrodes. Lens L1 Fourier transforms the angular deflection into a shift at the focal plane.
