Two-component spatial solitons in photonic crystal fibers

In this work, we study two problems associated with the theory of spatial optical solitons in PCFs. First, we analyze the properties and stability of two-component vector solitons excited in a nonlinear PCF and composed of two modes of different polarizations. Second, we consider a twin-core PCF with two nonlinear weakly coupled cores and analyze all-optical spatial switching of light between the two cores, for varying input intensity.
