Reconfigurable electro-optical logic gate to perform multiple logic operations

An EO logic gate comprising:

• a first MZI coupled between an optical input port and an optical output port;
• a second MZI optically coupled in parallel with the first MZI;
• a first phase shifter formed adjacent to the first MZI and coupled to a controller to receive a modulated first encoded electrical signal, and wherein the modulated first encoded electrical signal is generated by modulating a first encoded electrical signal based on a logic operation to be performed by the EO logic gate;
• and
• a second phase shifter formed adjacent to the first MZI and coupled to the controller to receive a modulated second encoded electrical signal, wherein the modulated second encoded electrical signal is generated by modulating a second encoded electrical signal based on the logic operation,
• wherein the first phase shifter and the second phase shifter apply phase shifts respectively to a first optical signal propagating through the first MZI and a second optical signal propagating through the second MZI based on the modulated first encoded electrical signal and the modulated second encoded electrical signal, and wherein the phase shifts cause an optical output at the optical output port to vary based on the logic operation of the first encoded electrical signal and the second encoded electrical signal.

A method comprising:

• modulating, by the controller based on the operation selection input, a first encoded electrical signal and a second encoded electrical signal to generate a modulated first encoded electrical signal and a modulated second encoded electrical signal;
• and
• applying, by the controller, the modulated first encoded electrical signal and the modulated second encoded electrical signal to the first phase shifter and the second phase shifter, respectively,
• wherein the first phase shifter and the second phase shifter apply phase shifts respectively to a first optical signal propagating through the first MZI and a second optical signal propagating through the second MZI based on the modulated first encoded electrical signal and the modulated second encoded electrical signal, and wherein the phase shifts cause an optical output signal at the optical output port to vary based on the logic operation of the first encoded electrical signal and the second encoded electrical signal.
