Abstract

We demonstrate a fast-responding Kerr phase gate using a room-temperature 85Rb vapor operated in a Raman gain scheme where the probe/signal wave travels “superluminally”. Continuously controllable nonlinear Kerr phase shift of the probe wave from 0 to π radian in comparison with a reference wave have been observed at 333o K (60oC). We show rapid manipulation of digitally encoded probe wave by using a digitally encoded phase control light field, demonstrating the capability of the system for possible application in information science and telecommunications.
