We demonstrate an optical current sensor that is based on the Faraday effect in gallium-substituted yttrium iron garnet and has a measured sensitivity of ∼3°/A, a noise-equivalent current of ~220nA/Hz, and a −3-dB bandwidth of ∼2.6 MHz. The bandwidth–sensitivity product is a factor of ∼10 greater than that of an all-silica-fiber current sensor with the same diameter.
