ABSTRACT:
A programmable optical logic gate for performing a selected function from the group including ALWAYS, NEVER, and logical OR, AND, NAND, NOR, XNOR, and XOR includes an optical logic circuit for receiving a first optical operand signal and a second optical operand signal and for performing a logic function on the first and second operand signals to produce an output signal, and further includes an optical logic function selection circuit coupled to the logic circuit for receiving logic function control signals and for selecting a logic function performed by the logic circuit on the first and second optical operand signals.
