Paper Abstract

An integrated optical gyrochip has been developed for industrial and consumer fiber-optic gyroscope applications. The gyrochip is pigtailed with low-cost elliptical-core polarization- maintaining optical fiber. An alignment technique was developed that uses image processing technology to align the polarization axis of the fiber without launching light into its core. The fiber-to-fiber insertion loss deviation of the pigtailed waveguide was less than +/- 0.8 dB at a wavelength of 0.78 micrometers over 100 temperature-change cycles, ranging from -30 to +80 degree(s)C, with a fiber mode-field size as small as 3.5 X 2.6 micrometers .
