A superconductor optical switch (100) comprising a superconductor microbridge (110), a bias current source, and a pulse current source. The superconductor microbridge is formed from a superconducting material wherein the superconducting material can transition at a critical level between a superconducting optically reflective state and a non- superconducting optically transparent state. When the bias current source is actuated and the pulse current source is not actuated, the superconductor microbridge is maintained in its superconducting optically reflective state. When the pulse current source is actuated concurrently with the bias current source being actuated, the superconductor microbridge is maintained in its non-superconducting optically transparent state. In different aspects, an optical system including the superconductor optical switch (100) can alternatively accept light that is either reflected from, or transmitted through, the superconductor optical switch as a switch signal. In different aspects, the critical level can be a critical electric current level, a critical magnetic flux level, or a critical superconductor temperature level.
