We investigate a new approach for the modulation of an optical signal based on the use of atomic coherence to control and enhance the response of the nonlinear medium. We describe a microscopic multi-level model of a medium driven by external fields and probed by a weak signal. We present explicit results describing the stationary behavior of this system, and outline a scheme for the analysis of its time-dependence. (C) 1997 The Franklin Institute.
