Design of Nonlinear Kerr Lens (NKL) and Method of Implementation of All Optical Logic Gates and Processors using a Single NKL
A design of nonlinear lens using Kerr effect is described. The incident light changes the focal length of the lens and this light induced focal length change are utilized to optical switching and routing. Using this type of lens all optical 3 input AND, X-OR and majority function logic gates, two input AND, X-OR, NAND, NOR, X-NOR, optical processors half Adder, Full Adder are implemented. Controlled operation of the logic gates is also explained.
