All-optical signal switching by Twyman Green interferometer with nonlinear frequency-doubling mirrors

Summary form only given. A nonlinear frequency-doubling mirror (NFDM) that consists of a frequency-doubling crystal and mirror situated behind it was investigated by us theoretically with respect to the phase and intensity of the reflected fundamental waves. We proposed this phase-shifting element to be used for construction of an all-optical switch based on a Twyman Green interferometer.
