Claim 0:
1. A transducer for receiving an optical signal and generating a digital representation of information modulated on the optical signal having a modulation bandwidth, comprising:
at least one optically-responsive superconductor circuit comprising an optically-responsive Josephson junction, configured to produce an asynchronous pulsatile electronic signal having a constant pulse rate in an absence of perturbation, and to have a variable pulse rate in excess of the modulation bandwidth corresponding to an intensity modulation of the optical signal;
a synchronizer, configured to synchronize pulses of the pulsatile electronic signal with a clock; and
a digital circuit configured to convert the synchronized pulsatile electronic signal into a multibit digital representation of the information.
