Bragg solitons and the nonlinear Schrodinger equation
01 January 1999
We develop explicitly the description of low-intensity Bragg solitons by the nonlinear Schrodinger equation. In contrast to earlier studies, this result is established for arbitrary soliton velocities. This result applies directly to grating solitons that have been observed in the laboratory. {[}S1063-651X(98)11212-6].
