| Abstract: | n integrated optical frequency shifter consisting of a pair of spherical geodesic lenses and two acousticsurface wave modulators for fiber-optic gyroscope using frequency modulation method was developed on theY-cut Ti: LiNbO3 planar waveguide. The frequncy shifting range was 10MHz. The center frequency wasl 07 MHz and drive power of the modulators was 200mW. |
