Abstract
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.

Hotspot monitoring system 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;
- wherein the first optical waveguide is attached to the superconductor to generate an optical path change for light propagating in the first optical waveguide to produce a change in the optical interference signal produced by the optical interference of the first optical signal and the reference optical signal, the optical path change in the first optical waveguide being generated when the superconductor transitions to a resistive state from a superconducting state.
