Original Abstract

In order to optical fiber linear birefringence compensation a promising method was chosen for pulsed current sensor design. The method employs orthogonal polarization conjugation by the back direction propagation of the light wave in the fiber. The Jones calculus analysis presents its propriety. Presented result is a new approach to the Jones calculus treatment in birefringent media. This approach simplifies the analysis. An experimental fiber optic current sensor has been designed and realized. The advantage of the proposed method was proved considering to the sensitivity improvement. The sensitivity has improved by a factor As = 174 in compare to the basic sensor setup. The detailed description of the experimental setup is described. For measurement of the sensor bandwidth a pulsed current source with very fast rise time is required. The description of the fast rise time current source design is presented also.
