Abstract

Electro-optic effect on periodically poled lithium niobate are used to develop different binary all-optical logic functions, such as NOT, buffer, OR, AND, NOR, NAND, XOR and XNOR circuits by varying the polarization state of the input optical signal around 90° on the plane of polarization using external electric field. Different performance parameters are estimated. Circuit parameters that are optimized have been chosen in order to construct the circuit practically. This approach has potential applicability in creating complicated logic functions by cascading many basic gates together.
