Abstract
Self-pulsing optical systems produce at constant input power P an output power PR (t)varying periodically with time t. Self-pulsing (SP) in nonlinear Fabry Perots and hybrid systems is well known. We reported the first known observation of SP in prism coupling into planar waveguides [1]. Recently we identified the physical mechanism of the SP and we shaved that SP occurs in a wider class of waveguide materials [2]. We also demonstrated that the same prism-waveguide system can exhibit SP, optical bistability (0B), and a special form of bistability (0B/SP), where at the same constant input power P the output power P is either constant in time or self-pulsing. In the present paper we present more experimental material and discuss the physical effects determining the system's behaviour.
