Abstract:

The nonlinear directional coupler NLDC is a promising element for ultrafast all-optical signal processing. The experiments have demonstrated self-switching of light in fiber-optic NLDCs, such as dual-core fibers, birefringent fibers, and periodically twisted birefringent filters. Fiber-optic nonlinear couplers exhibit an instantaneous Kerr-law response, which permits femtosecond pulse switching. Whereas with fiber-optic switches the switching power is relatively high, owing to the weakness of the fused quartz nonlinearity
