摘要：

A multifunctional, photonic-integrated circuit (PIC) is developed, specially designed for low-cost manufacturing of high-end tactical-grade fiber optic gyroscopes (FOGs). The PIC comprises functional integrated FOG components that compose the so-called "heart of the interferometer" based on a highly polarization-maintaining (PM) waveguide. FOGs with different fiber coil sizes are built using the PICs; the PIC FOGs are also called photonic gyros. A photonic gyro with a 110-meter-long fiber coil of 6cm diameter is demonstrated to have 0.59 degrees/hour/root Hz angle random walk, 0.048 degrees/hour bias drift, 15.44 ppm scale factor error, 0.24 degrees/hour bias instability, and 43.09 ppm scale factor instability over a temperature range of -40 to 75 degrees C.
