Optical bistability of a nonlinear microcavity

Abstract
Based on Fabry-Perot cavity's theories and efficiency refractive index,the optical bistability of a nonlinear microcavity is studied,and the corresponding mathematical formula are deduced.The theoretical curves are well fitted with those of numerical simulation in other papers.The investigation shows that appropriate frequency-shifting should be preset on the incident light in order to produce bistability for a nonlinear system.If the system is composed of focusing nonlinear medium,the frequency must be redshifted, otherwise it must be blue-shifted.The magnitude of critical shifting is 0.866 times of the width of microcavity resonance mode.
