Realization of all logic gates using hybrid grating structure: An application of silicon photonics

The outcome of present research work divulges all type of logic gates (NOT, AND, OR, XOR, NAND, NOR, XNOR) using two simple silicon grating structures, where plane wave expansion method manipulates to such structure to investigate the transmission characteristics. Output results infers that grating parameter such as number of layers, thickness of odd and even layer, the length of grating odd the proposed structure plays vital role to realize different type of optical logic gates.
