A Preliminary Study Of Micro-optical Gyroscope Ring Polymer Waveguide

The key targets of inertia navigation system are high precision and reliability, light weight and miniaturization. Gyroscopes become the emphatically developmental high technology in military and civilian application as key part of inertia navigation system. The integrated optic gyroscopes is the fourth generation gyroscope comparing Mechanical gyroscopes, ring laser gyroscopes and fiber optic gyroscopes, using waveguide to replace fiber and integrating source, splitting, detector, circuit processor and micro-optical accelerometer on the same wafer, then realizing small dimension and reliable operation.The most important technology of the MOG is to fabricate low loss waveguide and form alternative structure using coupling technology, and this will be mostly study in my article both in theory and practice. In this work, we report on the use of a novel mask-less laser-based micro-fabrication for the photochemical delineation of raised-rid waveguide in polymers and study the technics in details. By the control of power of LD and the time of exposal, we get the waveguide with the demanded profile and self-organized surface. The wide of waveguide and interrelated processing are discussed in theory and experiment.
