  • Abstract
    An integrated optical frequency modulator has been developed for a fibre-optic gyroscope using the frequency modulation method. A low insertion loss of 14 dB, which enables a 10¿6 rad/s sensitivity, was obtained by realising low coupling loss between the single-mode fibre and titanium-diffused LiNbO3 slab waveguide.
