Abstract

For the light source of the passive ring resonator fiber-optic gyro (RFOG), we have developed 1.3 micron highly coherent laser diode module (HCLDM) using resonant optical feedback from a compact hemispherical reference cavity. The HCLDM had the 100 KHz linewidth and was frequency-modulated by directly modulating the injection current. A FM spectroscopy technique was employed for rotation-sensing. The resolution of the present RFOG system was estimated to be 0.9 X tau exp -1/2 (deg./hour) (where tau is the integration time of measurement) from the signal-to-noise ratio of the demodulated signal.
