We propose equal output power dividers using nonlinear waveguide structure. By adjusting the branch angle, input power and the nonlinear coefficient, they could provide equal output power in each branch. The numerical analyses show that the results are correct.
We propose an all-optical logic device made of a bent waveguide with a Kerr-like nonlinear interface. It could provide an OR gate, exclusive-OR (XOR) gate and AND gate. We could obtain different transmission results by modifying the bending angle. The numerical simulation results show that the device functions as OR, XOR and AND gates.
