Multi-function Integrated Optic Chip (Y Waveguide Modulator)
Multi-function Integrated Optic Chip (Y Waveguide Modulator)
The multi-function integrated optical chip (MIOC, or Y waveguide modulator) is a key component in a fiber optic gyroscope (FOG) for measuring the angular velocity of an inertial navigation system. Fabricated on lithium niobate (LiNbO3), it combines a polarizer, a Y-junction coupler and dual electro-optical phase modulators. The waveguides are produced by the annealed proton exchange (APE) process. The device is widely used in high-sensitivity inertial navigation systems, with reliable performance over a wide temperature range.
