Abstract
An optical device for performing at least one Boolean logic operation. The optical device has at least a first and second input signal and at least one output signal. The optical device includes at least one interferometer for receiving the at least a first and second input signals. The device also has at least one optical amplifier for creating a phase difference between the first and second inputs to generate the output signal to perform at least one Boolean logic operation.
