Simultaneous all-optical 1's complement cum division-by-two schemes

Odd and even number detection is an important mathematical operation. Generally when any divisible by 2 then it called number, otherwise, odd number. Division can be easily obtained putting a point before the least significant bit of binary As example (27)10 = (11011)2 divided its result will (1101.1)2 (13.5)10. Hence we find fractional as logic-1 say that odd, even. This operation using demultiplexer. Here have developed optical circuit divide integer 2, apart from 1’s complement also circuit. Both results simultaneously. Terahertz asymmetric demultiplexer based switch plays very role to design this n-bit Numerical simulations are done performance
