ABSTRACT
The fundamental limitations for all-optical switching in a nonlinear directional coupler due to the saturation of the nonlinearity have been obtained by solving analytically the nonlinear coupled-mode equations. We found that there is a minimum value required for the saturation index change to obtain efficient switching, and that the number of powers at which switching occurs at one beat length can double.

    It is shown that a waveguide in the form of a channel of infinite length filled by a two-layer heavy fluid with a free surface can have nonpropagating waves (trapped vibrational modes) along with traveling waves. These waves are localized in the region of a dynamic inclusion, i.e., a solid block...
