Abstract

We studied the nonlinear propagation properties of a strong Gaussian pulse with the frequency close to the photonic band gap in fiber gratings by using the variational principle. Our results show that the width and the amplitude of the strong Gaussian pulse are unchanged with the propagation distance on the assumption that the Gaussian shape is inherently preserved, i.e. the strong Gaussian pulse has solitary-wave-like properties, at the same time, a linear chirp which changes with the propagation distance is generated.
