Paper Abstract

This paper demonstrates a novel fiber optic remote sensing system based on laser powering and a liquid-crystal optical modulator that transforms electrical signal of sensors into optical with low power consumption. A basic experiment for confirming the principle was conducted using a standard communication-grade semiconductor laser with the output of less than 20 mW both for laser powering and for sensor signal transmission. The sensor signal was transferred through 5-km-long optical fiber and detected with On/Off ratio of more than 15 dB.
