We report on a theoretical and numerical investigation of the switching of power in new hybrid models of nonlinear coherent couplers consisting of optical slab waveguides with various orders of nonlinearity. The first model ...

The coupling characteristics of a novel kind of directional couplers composed by two parallel non-conventional waveguides are theoretically analyzed in details.The coupling length as a function of the operating wavelength ...

We demonstrate how to improve the switching power and performance of all-optical nonlinear couplers by introducing linear control waveguides. In particular, we demonstrate this idea for a three-core coupler consisting of ...

In this work, we present a numerical design of a pedestal waveguide as a suitable alternative for coupling between few-mode fibers and integrated devices. The proposed waveguide has a cylindrical core deposited over a ...
