Paper Abstract

We demonstrate the generation of solitons in the photorefractive materials with strong optical activity and absorption. The general wave equations are processed by rotation and affine transformations in order to decouple the effects of photorefractivity and optical activity. Analytical solutions of these equations are found in the case of slowly varying envelope and low-intensity approximations. The solutions show the occurrence of breathing solitons in sillenite crystals with strong optical activity and absorption in a particular orientation with respect to the external electric field. The absorption is decreasing the soliton intensity with the propagation distance (which set a limit in the soliton channel length) and is increasing the breathing period.
