Abstract
We demonstrate an optically controlled Kerr phase shifter using a room-temperature vapor operating in a Raman gain scheme. Phase shifts from zero to relative to an unshifted reference wave are observed, and gated operations are demonstrated. We further demonstrate the versatile digital manipulation of encoded signal light with an encoded phase-control light field using an unbalanced Mach–Zehnder interferometer. Generalizations of this scheme should be capable of full manipulation of a digitized signal field at high speed, opening the door to future applications.
