✦ Synopsis

A novel method for simultaneous measurement of current and voltage employing a single monomode low-birefringence (Lo-Bi) ®ber is described. This uses the Faraday eect for detection of current and the Kerr eect for detection of voltage. The waveform of the output light intensity due to the Kerr eect has been detected and the Kerr constant was measured as 5.4 Â 10 À 16 m/V À 2 at 258C. Theoretical analysis shows that the current component can be measured free from the in¯uence of the voltage component and the two components can be easily separated.
