The Sagnac interferometer as a two-parameter sensor

We show the Sagnac interferometer as a two-parameter sensing device where nonreciprocal and reciprocal effects can be independently and simultaneously monitored. Phase shifts induced by nonreciprocal effects affect differently the counterpropagating beams in the loop and are accurately detected by a...
