All-Optical Switch and Transistor Gated by One Stored Photon
All-Optical Switch and Transistor Gated by One Stored Photon
The realization of an all-optical transistor, in which one "gate" photon controls a "source" light beam, is a long-standing goal in optics. By stopping a light pulse in an atomic ensemble contained inside an optical resonator, we realized a device in which one stored gate photon controls the resonator transmission …
