Nonlinear Optical Materials and Applications.

Abstract

Characteristics of the photorefractive effect in semiconductors were investigated for applications in optical signal processing. Nonstationary recording techniques of moving gratings and alternating electric fields were examined numerically and experimentally. The dependence on modulation depth was studied in detail. Saturation effects at large modulation limited the enhancement of these nonstationary recording techniques. The photorefractive properties of the II-VI semiconductors ZnTe:Mn:V and Cd (0.55) Mn(0.45) Te:V were characterized. These materials provide good response in the near infrared.
