Abstract: A similarity transformation is utilized to reduce the generalized nonlinear Schrödinger equation (NLSE) with variable coefficients to the standard NLSE in space-time modulation photonic crystal lattice, whose soliton solutions are then transformed back into the solutions of the original equation. Special kinds of explicit solutions, such as periodically breathing bright and dark solitons, are discussed in detail.

Key words: nonlinear optics, spatial solitons, photonic crystal lattice
