It is based on the reduction of the intensity threshold of the switch. Obtained results indicate that the required intensity threshold depends on the reflectivity coefficients of its Fabry-Perot cavity and the absorbance of the intercavity nonlinear medium. It has been tried to optimize the switch parameters such that the intensity threshold is significantly decreased. Finally the effects of the intensity profile of a laser beam on a bistable optical switch produced by using a carbon sulfide (CS) are investigated.
