Abstract
Photorefractive materials possess features (strong response at low power levels and parallel processing) which are convenient for realization of optical circuits that are functionally similar to different electronic devices. These advantages are used to propose an optical transistor based on a bidirectional PR ring resonator, whose operation is functionally similar to the operation of a bipolar junction transistor. Also included are the transverse effects in the analysis of PR ring cavity. This is important for the parallel operation mode of optical processors. It is observed that under variation of the Fresnel number the signal beams form different mode structures in the transverse plane. For low reflectivities of the cavity mirrors bistability is observed. This effect can be utilized to build other optical oscillators, such as flip-flop. Both solutions can be stabilized when transverse dimensions are taken into account.
