ABSTRACT:
An optical control system and method comprised of obtaining optical bistability by radiating a crystal with both the exciton energy level and the excitonic molecule energy level as the optical excition energy level, with a laser beam having energy less than (Em/2-.gamma.), in which Em is the excitonic molecular energy level, an .gamma. is the half-amplitude level of absorption spectrum of two-photon resonance. The advantage of optical bistability is that high speed switching of an order of pico-seconds is possible due to the coherent non-linear response, and that switch-on and switch-off energy required is less than pico-Joule.
