Abstract :
We have studied theoretically the transmission of lightwave through cascaded nonlinear directional couplers with two-input excitations. Various types of all optical logic operations including AND, OR, XOR, NOR, NXOR, and NAND are available in the same cascaded nonlinear fiber coupler structure.
