Paper Abstract

Fiber optic gyroscope is a completely static, pure optical gyroscope, with a high resolution and other advantages. In order to make the Fiber optic gyroscope be smaller in size, more reliable and sensitive, this paper presents a new type of interference integrated optical chip, which is X-cut and Y-propagation LiNbO3 substrate with the dimensions of 38mm×6mm× 2mm. We research and design Double-Y branching guide, phase modulator and polarizers of Integrated Optical Chip in FOG. Double-Y branching waveguide, phase modulator and polarizers were integrated in a chip, on which sensing element, resource (SLD), electrophotonic detector (PIN) and signal demodulation circuit are hybrid-Integrated together, then we get an acceleration FOG of high resolution. We test the chip with input light and find that diffraction image of output light from the double-Y branching waveguide is well symmetric, which indicates that the double-Y branching waveguide is 3dB beam-splitting, to overcome deficiencies of fiber coupler of splicing type and dual-melting conical. Exciting signal is coherent with the output signal of the FOG, and the performances of the FOG meets design requirement.
