Abstract

The usage of Nematic Liquid Crystal (NLC) infiltrated Photonic Crystal Fibers (PCFs) for a low cost, all-fiber, high voltage sensing device is experimentally demonstrated. The infiltrated PCF which transmit light based on the photonic bandgap mechanism is employed in an intensity based all-fiber voltage measurement scheme, by applying the voltage perpendicular to the fiber axis. The output transmittance of the PCF varies linearly with increasing voltage. The PCF voltage sensor is capable of measuring high voltages in the range from 100 V to 850 V. The voltage sensing device is compact and exhibits accurate voltage measurement owing to its intrinsic nature with the NLC material infiltrated within the air-holes of the PCF microstructure.
