Abstract
We discuss an electronic circuit that simulates wave propagation in dispersive media. The circuit is an array of phase shifters composed of operational amplifiers. The envelope of the simulated light pulse can be described by a discretized version of the one-dimensional wave equation. The circuit can be used to change the group velocity both spatially and temporally and emulate slow light or stopped light. The control of the group velocity of optical pulses is expected to be a useful tool for quantum information and communication.
