Zusammenfassung:Chip-scale interferometric fiber optic gyroscope (IFOG) has caught growing attention for its huge application potential in the low-cost consumer electronics market. In this paper, a novel three-axis IFOG is proposed and assembled with an integrated coupler chip (ICC) fabricated on the silica platform. The ICC realizes bidirectionally multichannel optical interconnection without waveguide crossings. The test results indicate the weak wavelength dependence and comparatively low insertion loss at 0.85μm of the ICC. With ~900m polarization-maintaining fiber coils, the three-axis IFOG exhibits a long-term stability of
