Abstract
An investigation is performed of the formation of parametric optical solitons in a Bragg structure doped with active elements with quadratic nonlinearity. Numerical modeling is used to show that competition between nonlinear coupling, Bragg reflection, and additional gain/absorption profile generally leads to an asymmetric picture of the propagation of two-frequency solitons.
