Simultaneous logic operations and their inverse in a single circuit using simple optical components

Logic units are the basic building blocks of many complex computational operations. In this paper an optical circuit using simple optical components has been proposed which is capable to perform all 16-optical logic (two variables) operations without changing the design of the circuit. The circuit has two outputs, one is complement to the other and hence optical input data must be at any one output. So, no data loss happens during the operation.

► Logical operation and its inverse in a single circuit are proposed using optical components.
► This circuit performs all 16-optical logic (two variables) operations without changing the design of the circuit.
► This circuit is very simple.
► Numerical simulations using the data sheet of some commercially available optical products has also been done.
