Optical XOR-XNOR logic circuits using mechanical movable mirrors

Using movement of mirrors mechanically one can easily create the different path for light. In this paper, we have performed three-variable XOR and XNOR logical operations using mechanical movable mirrors. It is utilized in basic computerized expansion circuits which figure the entirety and convey of two bit or three bit numbers. XOR entryways are additionally used to decide the equality of a parity of binary number, i.e., if the all out number of 1's in the number is odd or even. The XNOR rationale gates are utilized in mistake identifying circuits which are to recognize odd parity or even parity bits in advanced information transmission circuits. XNOR entryway is basically utilized in arithmetic and encryption circuits. This simple design can be easily fabricated into chip level.
