Abstract
A system for estimating a parameter selected from the group consisting of a current, a magnetic field, or combinations thereof comprises a resonant frequency tunable magneto-optical loop resonator, wherein the loop resonator comprises a magneto-optical sensing element coupled to an optical waveguide, and wherein the loop resonator is configured for receiving an originating optical signal from a broadband light source and providing a modulated signal indicative of the estimated parameter.
