Claim 19:
20. A transducer for receiving a wavelength division multiplexed optical signal and generating digital representation of information modulated on different channels of the wavelength division multiplexed optical signal, comprising:
a plurality of microring resonators, each microring resonator having a respective resonance to allow a respective channel of the wavelength division optical signal at a respective wavelength and having a modulation bandwidth; and
a plurality of optically-responsive superconductor circuits, each respective optically-responsive superconductor circuit being associated with a respective microring resonator,
each respective optically-responsive superconductor circuit comprising:
an optically-responsive Josephson junction, configured to receive the allowed respective channel of the wavelength division optical signal of a respective microring resonator and, to produce an asynchronous pulsatile electronic signal having a constant pulse rate in an absence of optical signal intensity, and a variable pulse rate in excess of the modulation bandwidth of a respective channel of the wavelength division multiplexed optical signal and corresponding to the information modulated on the respective channel of the wavelength division multiplexed optical signal;
a clocked synchronizer having a synchronized pulsatile electronic signal output; and
a digital circuit configured to convert the synchronized pulsatile electronic signal output into a multibit digital representation of the information modulated on the respective channel of the wavelength division multiplexed optical signal.
