Abstract

The nonlinear directional coupler is one of the most promising-all-optical switch devices as it has two input and output channels. This device has been analyzed both by means of the coupled mode theory and by the beam propagation method.1 In this paper, in order to study also the case of nonlinearity with high variations in the index of refraction, we analyze it with a full vectorial finite-element based code.2
