title: Generating Bragg solitons in a coherent medium.
abstract: In this paper we discuss the possibility of producing Bragg solitons in an electromagnetically induced transparency medium. We show that a coherent medium can be engineered to be a Bragg grating with a large Kerr nonlinearity through proper arrangements of light fields. The parameters of the medium can be easily controlled through adjusting the intensities and detunings of lasers. This scheme may provide an opportunity to study the dynamics of Bragg solitons with low power lights.
