Devices and methods for electromagnetic signal phase discrimination using SQUID arrays and electro-optical materials

An electromagnetic signal is received at first and second Superconducting Quantum Interference Device (SQUID) SQUID arrays. The first and second SQUID arrays output respective voltage signals corresponding to the electromagnetic signal as received at the first and second SQUID arrays. The first and second SQUID arrays are spaced apart such that there is a phase difference between the electromagnetic signal as received at the first and second SQUID arrays. The phase difference results in a voltage amplitude difference. At least one of the voltage signals is applied to at least one reference optical signal input into an electro-optical device to modify the reference optical signal. The modified optical signal output by the electro-optical device includes a change compared to the reference optical signal. The change is indicative of the phase difference in the electromagnetic signal as received at the first and second SQUID arrays.
