Abstract

A method using photoelectric effect of a single-mode optical fiber, with a 632.8nm He-Ne laser, has been developed for the simultaneous measurment of current and voltage. The Magnetic stress for the current and the piezoelectric effect for voltage are utilized. It is found that the detector output voltage is proportional to the square of the applied current and the frequency of the output is twice of that of the applied current.
