ABSTRACT:
An optical transistor comprising two semiconductor lasers 1, arranged in a nonlinear ring vibrator 2, and two strip waveguides 3, each of which has a region A of optical coupling with the nonlinear ring vibrator 2, positioned on a common substrate. The regions of optical coupling are positioned diametrically opposite each other. The semiconductor lasers 1 have electrodes 4 for power supply. Each region A of optical coupling is provided with a control electrode 5 and each section of the nonlinear ring vibrator 2, located between the semiconductor 1 and corresponding regions of optical coupling, is also provided with a control electrode 6. Mirrors 7 form vibrators for the semiconductor lasers 1.
