Abstract: PROBLEM TO BE SOLVED: To provide an optical device for executing an arithmetic function as a coupling type Boolean logic operation, and to provide the optical device for ciphering and deciphering data. SOLUTION: This optical device is an optical device (50) for performing at least one Boolean logic operation and the device (50) has at least first and second input signals (54, 58) and at least one output signal (OUT). The optical device includes at least one interferferometer device for receiving at least the first and second input signals and also has at least one optical amplifier (64, 66) generating an output signal for executing at least one Boolean logic operation, by creating a phase difference between inputs of the first and second input signals.
