摘　　要：介绍了一种光纤陀螺用细径宽带保偏光纤耦合器。采用预拉伸技术增加了保偏光纤耦合器的带宽,采用"无拉伸熔锥"技术降低了保偏光纤耦合器的损耗。该保偏光纤耦合器尾纤包层直径为80μm,涂覆直径为160μm,带宽大于70nm。A small-diameter wide-band PM fiber coupler （PMFC）for fiber optic gyroscope is introduced. Prestretching technology is used to broaden the bandwidth of PMFC, and ＂no tension fused taper＂ technology is used to reduce the loss of PMFC. The cladding diameter of the tail-fiber is 80 μm, the coating diameter of tail-fiber is 160μm, and the bandwidth of PMFC is greater than 70 nm.
