摘　　要：在高Q值法布里 珀罗腔中研究了二阶串级非线性相移 .结果表明 ,通过改变入射光强 ,可以全光学控制基频光束的透射率和它的相移 .基频透射光束的非线性相移相对入射光强的变化率被提高了腔精细度的平方 .这可用作光子学开关器件 .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.
