Hotspot monitoring system for superconducting devices including: - a superconductor; - a first optical waveguide attached to the superconductor for providing a first optical signal; - a second optical waveguide for providing a reference signal; and - interference means configured to overlay or superimpose the first optical signal and the reference optical signal to produce an optical interference signal.
