Table-top mirror based parallel programmable optical logic device

Light rays can easily be reflected to different path by mechanical movement of mirrors. Using this basic operational principle we can design parallel programmable optical logic device (PPOLD) by arranging mirrors on a table. The 'table-top mirror' models of this proposed circuit have been shown here. We can program it to design all the two input 16-Boolean logical expressions from a single design. The design is based on only plane mirrors. No active optical material is used in this design. Not only that the proposed circuit is optically reversible in nature. Moreover this design is very simple in sense. It can be fabricated in MEMS based optical switches.
