Achieving All-optical Diode through Non-symmetrical Nonlinear Cavity and the Effect of Photon Tunneling

摘要

Basing on the effect of photon tunneling, we have studied the transmission properties of a non-symmetrical nonliear cavity through transfer matrix method. It is found that a unidirectional diode-like transmission occurs with this structure. For the same incident frequency and incident intensity, while light is at switch-up status for left incidence, the light is at switch-down status for right incidence.
