All-optical 'AND' gate using gap soliton formation in a fiber Bragg grating

Summary form only given. We present, for the first time to our knowledge, an all-optical 'AND' gate based on a configuration proposed by S. Lee and S.T. Ho. [see Opt. Lett., vol. 18, p. 962, 1993]. The operation of the gate relies on the formation and propagation of coupled gap solitons by two orthogonally polarized high-intensity input beams incident within the bandgap of a fibre Bragg grating (FBG).
