Abstract:

All-optical logic gates have been demonstrated using nonlinear waveguide devices. In such devices, optical fibers are increasingly used, since their optical Kerr effect is very fast, and their low-loss waveguide structure allows a long interaction length and relatively low power. For example, an AND gate based on intensity-dependent polarization rotation, XOR and AND gates based on soliton trapping, a NOR gate based on soliton dragging, and AND, NOT, XOR, and XNOR gates have been demonstrated in polarization-maintaining fibers.
