Multi-function Integrated Optical Chip (MIOC), 1550 nm, Low Drive (Space Qualified)

PART NUMBER : MIOC-1550-SP

The multi-function Integrated Optical Chip (MIOC) is the key component in many fiber optic sensing solutions, i.e. Interferometric Fiber Optic Gyroscope (IFOG) for measuring the angular velocity of an inertial navigation system and the Optic Current Sensor (FOCS) for measuring electric current in power systems. The MIOC consists of a polarizer, a Y-junction coupler, and dual electro-optical phase modulators. It is often fabricated on an X-cut single-crystal lithium niobate (LiNbO3) wafer. We use the Annealed Proton Exchange (APE) process to fabricate the optical waveguide of an MIOC along the Y direction of the crystal structure. Featuring over 60 dB Polarization Extinction Ratio (PER) and highly reliable chip-fiber coupling, Our MIOC product can minimize bias drift resulting from polarization crosstalk-induced non-reciprocity. The MIOC passes satellite environmental qualification test project such as temperature, vibration, shock, thermal and radiation test, making it qualified for space laser communication.
