The gain-bandwidth of hybrid optical transistors

A small-signal analysis for the optical gain of hybrid optical transistors is presented. The adjustment of the operating conditions of the nonlinear optical transmission element is compared for both the Fabry-Perot resonator and the mirrorless electrooptic modulator. The optical gain-bandwidth product is obtained for both first-order and second-order feedback electronic circuits. This product is proportional to the circuit bandwidth. The effect of quadratic electronic nonlinearity on the operation is given.<
