Abstract

The invention of electronic transistors revolutionized the field of electronics. There have been many attempts to achieve transistor action in different optical circuits [1]. 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 [2]. We use these advantages 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.
