Optical logic gates using binary decision diagram with mirrors

Optical circuits of different logical operations using binary decision diagram (BDD) are proposed and described in this paper. A simple table-top model using plane mirrors based on this architecture has been shown in this manuscript. This model is the macroscopic form of micro-electromechanical (MEMS) optical switch, which is also described in this manuscript. Numerical simulations using torsion type micromirrors have been done to find its operational performance. The design is simple and easy to implement for higher bit also.
