Nonlinear phase-shift in a high- Q Fabry-Perot cavity induced by cascaded second-order effect
高Q法布里-珀罗腔中二阶串级非线性相移

We examine the nonlinear phase shift in a high Q Fabry Perot cavity induced by cascaded second order effect. The result shows that all optical control of transmissivity and phase shift of a fundamental beam is possible, based on resonance enhancement, through changing input intensity. The derivative of the nonlinear phase shift of the fundamental transmission beam with respect to input intensity is enhanced by the square of resonator fineness, which allows for photonic switching devices.
