LiNbO3 MIOC Y-Waveguide Integrated Optical Devices For FOG / FOCS

LiNbO₃ MIOC Y-Waveguide Manufacturer | Integrated Optical Device for FOG & FOCS | Gracyfiber

1. Product Overview

  Gracyfiber LiNbO₃ MIOC (Y-Waveguide) is a compact and high-stability integrated optical device designed for precision sensing and electro-optic modulation applications.
Fabricated on optical-grade lithium niobate wafers using microelectronic processing, the device integrates waveguides and electrodes on a single chip platform. Input and output fibers are precision angle-coupled to the waveguide, and the chip is packaged in a gold-plated Kovar housing for reliable long-term use. The device can perform polarization, beam splitting/combining, and phase modulation functions, making it suitable for fiber optic gyroscopes, fiber optic current sensors, hydrophones, and other fiber sensing systems.
