在频率调制光纤陀螺中使用的集成光学频率调制器已有所发展。通过降低单模光纤与渗钛LiNbO_3波导之间的耦合损耗,可以获得低于14dB的插入损耗。这相当于灵敏度为10~(-6)rad/s。
Integrated optical frequency modulators for use in frequency-modulated fiber optic gyros have been developed. By reducing the coupling loss between the single-mode fiber and the titanated LiNbO_3 waveguide, an insertion loss of less than 14 dB can be obtained. This corresponds to a sensitivity of 10 -6 rad / s.
