    Abstract

    In this paper, we demonstrate through simulation a low - cost, high - speed optical voltage sensing system with a multiplexing capability. The scheme utilizes transducers based on a hybrid piezoelectric/ optical construction, whereby the optical power reflected from dual - peak fiber Bragg gratings is modulated in response to an excitation voltage and monitored by photodetection while remaining robust to fluctuations in optical power and temperature. A dedic ated solid - state interrogation system incorporating passive wavelength division multiplexing allows for high - speed measurement over the ac/dc voltage sensor array without the use of expensive components, such as tunable filters or lasers .
