Document Type and Number:
WIPO Patent Application WO/2023/106687
Kind Code:
A1
Abstract:
Disclosed is an integrated optical system-based photocurrent sensor system. The present invention comprises: a light source for generating reference light for current or magnetic 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 light guided through an optical path at the end of an optical fiber, wherein the present invention further comprises: a plurality of optical fiber pigtail blocks in which the optical fiber is accommodated therein; and an integrated optical system composed of a plurality of optical elements optically bonded to each other at interfaces with the pigtail blocks.
