Paper Abstract

In this contribution we focus on thermally induced absorptive optical nonlinearities in II-VI semiconductors. We demonstrate an optical oscillator by introducing the sample into a hybrid ring resonator with long round trip time. In the case of only marginally bistable input-output characteristics (realized with a CdS single crystal) we get the following dynamical behavior: For high input intensities the oscillation period is a multiple of the delay time. When decreasing the input intensity relaxation oscillations that stabilize the system and prevent it from a transition to deterministic chaos become important. Additionally we investigate the spatiotemporal dynamics of the system if a large diameter holding beam is switched by a small and short light pulse. Here we find switching waves and metastable temperature profiles.
