In this paper we present our investigations concerning thermally induced optical bistability (OB) in CdS and ZnSe. With CdS platelet type single crystals basic boolean functions are realized. The possibilities of cascadability and parallelity of the information processing and the switching dynamics of the system are examined. Further on the effect of optical noise upon the switching process and the instable branch of the hysteresis loop are measured. In ZnSe both absorptive and dispersive OB are observed. An efficient opto-electric modulator is built using the photothermal SEED-effect.
