Abstract

Low-contrast all-optical Zeno switching has been demonstrated in a Si₃N₄ microdisk resonator coupled to warm atomic vapor. The device is based on the suppression of the resonant microcavity field buildup due to nondegenerate two-photon absorption. This experiment used one beam in a resonator and one in free space due to limitations related to device physics. These results suggest that a similar scheme with both beams resonant in the cavity would correspond to input power levels below 150 nW.
