Hybrid Bistable Devices

Considered in the present chapter are the regimes of the hybrid bistable scheme, which is an electro-optic modulator in which a part of the power of the transmitted radiation is transformed into an electric voltage which is applied then through the feedback circuit to the electro-optic crystal. The transverse distributivity is not essential in this scheme, and the longitudinal one shows itself in the form of a delay. Neglecting the response (relaxation) time in the feedback circuit, the kinetics of the scheme is described by one-dimensional point mapping, which connects the system characteristics in a time interval equal to the delay time. Then, at a constant power of incident radiation and with an absence of noise, stationary, periodic (with the period being a multiple of the delay time) and dynamically chaotic regimes form depending on the parameters and initial conditions of the scheme. A finite response time leads to a shift of stability boundaries for these regimes, to an increase in the modulation period, and, for the chaotic regimes, to a breakdown of the output radiation into pulses with a duration of the order of the response time.
