Abstract
We demonstrate an optically controlled Kerr phase shifter using a room-temperature Rb85 vapor operating in a Raman gain scheme. Phase shifts from zero to 𝜋 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.Citation
