1. An optical transistor comprising:

  • a nonlinear ring vibrator and at least one pair of strip waveguides, positioned on a common substrate, each pair having a region of optical coupling with said nonlinear ring vibrator,wherein said regions of optical coupling corresponding to said pair of strip waveguides are positioned diametrically opposite each other,in which in order to expand the functional possibilities by obtaining bistable characteristics and a differential gain having a steep slope, additionally provided are at least two semiconductor lasers positioned in said nonlinear ring vibrator outside said regions of optical coupling,wherein each of said regions of optical coupling and each section of said nonlinear ring vibrator, located between said semiconductor lasers and said regions of optical coupling, are provided with control electrodes.
