Overview

Multi-function integrated optical chip (MIOC, or Y Waveguide Modulator) is a key component in Fiber Optic Gyroscope (FOG) for measuring angular velocity of an inertial navigation system. This integrated device, fabricated on Lithium Niobate (LiNbO3) material, is composed of a polarizer, a Y-junction coupler and dual electro-optical phase modulators. Waveguides on the chip are produced by the Annealed Proton Exchange (APE) process. This MIOC device has been used in a lot of high-sensitivity inertial navigation systems to detect angular velocity . It has highly reliable performance with wide temperature range tolerance.
