Abstract

We already discussed the bistable behavior of a Fabry Perot resonator filled with molecular media as well as the characteristics of a spatial light modulator (SLM) based on the nonlinearity induced by excited state absorption. In the present paper we present two practical configurations. First we analyze a cavity-less bistable element which removes some of the realization problems related to high finess cavity. In this configuration the nonlinear medium is located in one arm of an optical interferometer. The scheme provides the required amount of positive feedback by the bistable mechanism -- but without a cavity. We applied the nonlinear eikonal approximation, a method which takes care of the detailed propagation effects, and obtained conditions for bistability, as well as optimizing the design parameters such as the output mirror reflectivity, etc.
