Abstract : An optical switching device employs a rare earth bis-phthalocyanine having good third-order nonlinear susceptibilities. In a preferred optical switch, the rare earth bis-phthalocyanine is employed as a nonlinear optical material body that fills the space between two partially reflecting mirrors. When light incident on the switch is below a given intensity level, light passes through the switch and the switch is in an open state. When light is above a given intensity level, light is trapped in the nonlinear optical material and the switch is in a closed state.
