Paper Abstract

We describe a fiber optic voltage sensor with optically controlled sensitivity.The sensor operates at two widely separated wavelength (633nm and 976nm) one of whichis a control signal (976nm).We show that at a properly chosen wavelength of the control signal and of the phase-retarding element, variation of the control signal allow increase or decreases in the sensitivity of the sensor.A theoretical analysis of sensitivity as a function of the optical power of a control signal is presented. WE have demonstrated experimentally variation of the sensor ,s sensitivity from 0.01% to 0 per 1Vms of control power change in the range of 0÷7 ?W.
