Abstract :
We propose all-optical logic gates by using a multibranch waveguide structure with localized optical nonlinearity. By simply setting nonlinear media in the selected output guides and properly launching the input power, the numerical results show that the proposed all-optical waveguide structure could really function as AND and OR logic gates.
