A method for transforming fast solitons into slow ones in bandgap fibers is proposed. The approach is based on the deceleration of the solitons by intrapulse Raman scattering, which can be achieved for fiber modes having a cutoff frequency. We develop a comprehensive theory for the soliton slowdown and elucidate how the fiber losses introduce a fundamental minimum for the soliton velocity.

    ABSTRACT: Microstructured optical fibers based on As2Se3 glass may be designed to have an in-plane photonic bandgap, and thereby support modes with zero propagation constant and zero group velocity. It has been shown that such structures will support gap solitons which by way of Raman scattering will be driven towards the zero velocity state. An important question in connection with slow-light propagation is the influence of waveguide imperfections, which typically leads to a strong scattering of the slow light as the group velocity tends to zero. Theoretical investigations of this subject have so far focused on the experimentally realized case of planar photonic bandgap waveguides, where the imperfections are present on a subwavelength scale given by the lattice periodicity. In microstructured fibers, however, the deformation spectrum can be expected to be of an entirely different nature, with long-period perturbations playing a dominant role. The purpose of this work is to investigate how such long-period perturbations will affect the propagation of slow-mode optical solitons.

    ABSTRACT: Soliton propagation in slow-light states of nonuniform high-index photonic crystal fibers (PCFs) is studied numerically by a recently developed time-propagating 1 + 1 D equation. It is demonstrated that very slow solitons can be highly stable against even short-period roughness. Soliton trapping by longitudinal inhomogeneities is also found as the soliton velocity decreases due to Raman scattering. Practical limitations and opportunities based on the simulation results are briefly discussed.

    ABSTRACT: The influence of Raman scattering and higher order dispersions on solitons and frequency comb generation in silica microring resonators is investigated. The Raman effect introduces a threshold value in the resonator quality factor above which the frequency locked solitons can not exist and, instead, a rich dynamics characterized by generation of self-frequency shift- ing solitons and dispersive waves is observed. A mechanism of broadening of the Cherenkov radiation through Hopf instability of the frequency locked solitons is also reported.
