Claims4
Superconducting A/D converter apparatus comprising:
- a superconducting A/D converter of the type having at least one input adapted to receive an electrical input signal, and at least one output adapted to generate an electrical output signal;
- at least one input light guide for providing an input analog signal;
- at least one output light guide for providing an output digital signal that varies according to said input analog signal;
- at least one optoelectronic transducer having an input coupled to at least one input light guide of said superconducting A/D converter and an output coupled to said input of said superconducting A/D converter;
- at least one magneto-optical transducer coupled to an output of said superconducting A/D converter and an output coupled to said output light guide;
- whereby the input and output light guides are utilized to reduce thermal losses in the superconducting A/D converter apparatus.
