Abstract
Provided is an integrated optical system-based optical current sensor system comprising a light source generating reference light for current or magnetic field sensing, a polarizer for polarizing the reference light, a phase modulator for phase-modulating the polarized light into a predetermined reference signal, and a Faraday rotation reflector for reflecting the light propagated through an optical path at the end of the optical fiber, wherein the invention further comprises a plurality of pig-tailed optical fiber blocks in which the optical fibers are accommodated therein, and an integrated optical system composed of a plurality of optical components optically bonded to the pig-tailed blocks at interfaces with the pig-tailed blocks.
