Abstract
An example optical system having an electro-optical (EO) logic gate connected to a controller is presented. The controller modulates a first encoded electrical signal and a second encoded electrical signal based on an operation selection input. The EO logic gate includes a first Mach Zehnder interferometer (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 adjacent to the first MZI and; and a second phase shifter adjacent to the second MZI. The phase shifters apply phase shifts to the optical signals propagating via the first and second MZIs based on the modulated first encoded electrical signal and the modulated second encoded electrical signal to 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.
