SELF-OSCILLATIONS AND OPTICAL CHAOS OF AN INDUCED ABSORBER IN COUPLED CAVITIES

Abstract

In this paper we investigate the nonlinear dynamics of an induced absorber (CdS) in two coupled, hybrid, optoelectronic ring-cavities. By changing the cw-pumping intensity an inverse successive-subharmonic-oscillation cascade followed by a chaotic oscillation is experimentally observed with a narrow bistable input-output characteristics of the absorber. The related numerical simulations are given. For fixed delayed times a new type of frequency hysteresis is found. In the case of one very short and one very long delay time, a series of mixed self-oscillation modes, which is composed from the modes corresponding to the two delay times, is observed.
