Multi-Functional Integrated Optical Chip - MIOC
The Optilab MIOC is the key component of Fiber Optic Gyroscope (FOG) for rotational rate sensing and inertial navigation systems. This Integrated Optic Chip (IOC) device is composed of a polarizer, a Y-junction coupler and dual electro optic phase modulators. Based on Lithium Niobate (LiNbO3), MIOC is fabricated with High Temperature Proton Exchange (HTPE) optical waveguides. The MIOC features Polarization Extinction Ratio (PER) exceeding 60 dB that can minimize bias drift which results from polarization crosstalk induced non-reciprocity. The MIOC assures high reliability and performance over wide temperature range.
