GAP SOLITON PROPAGATION IN OPTICAL-FIBER GRATINGS

Intense optical pulse propagation in a GeO2-doped silica glass fiber g rating results in nonlinear pulse propagation velocities and increased transmission at wavelengths where the grating reflects light in the l inear limit. These nonlinear pulse propagation effects are predicted b y numerical simulations of gap soliton propagation. The large linear r efractive-index variations used for the fiber gratings in these experi ments permit the propagation of gap solitons in short lengths of fiber . (C) 1995 Optical Society of America
