title: Optimal design of optical fibers for electric current measurement.
abstract: The current sensitivity and bandwidth of the optical fiber current monitor are analyzed. The optimal sensitivity is proportional to the ratio of fiber attenuation to the Verdet constant at a specific fiber length. A selection of compound glasses has been investigated with a view to improving bandwidth and sensitivity over standard silica-fiber systems. A trial fiber of the most promising glass (Schott F7) has been fabricated and characterized.
