光纤陀螺是一种完全静止型的光学传感器，为了进一步缩小它的体积，提高它的性能，将其光学处理部件集成光学化是必不可少的．GaAs材料具有优良的温度特性，抗辐射特性，以及优良的材料生长特性和微细加工特性，特别适合于要求高的光纤陀螺用的集成光学器件的研制。本文报导了工作于1．3μm光波波长，分束比为50：50（±5％），相位调制宽达到1GHz，半波电压小于10V，偏振器消光比大于60dB的光纤陀螺用集成光学器件的理论研究和实验研究的结果。
FOG is a completely static type of optical sensor, in order to further reduce its size and improve its performance, the optical components of its optical integration is essential. GaAs materials with excellent temperature characteristics, anti-radiation properties, and excellent material growth characteristics and micro-processing characteristics, especially suitable for demanding optical fiber gyroscope integrated optics development. In this paper, we report the performance of integrated optics for fiber optic gyroscopes operating at a wavelength of 1.3 μm with a 50:50 (± 5%) splitting ratio, a wide phase modulation of 1 GHz, a half-wave voltage of less than 10 V and an extinction ratio of polarizer greater than 60 dB Theoretical research and experimental research results.
