Abstract

The use of proton-exchanged LiNbO₃ waveguides as an alternative to titanium-diffused waveguides in fiber optic gyro (FOG) circuits is investigated. The proton-exchanged FOG circuits offer far superior polarization control and reduced fiber-to-fiber insertion loss without any degradation in the electrooptic properties of the LiNbO3. A pigtailed three-port FOG circuit operating at 1.55-micron wavelength is demonstrated which exhibits <5.5 dB fiber-to-fiber loss, polarization extinction >60 dB in the chip and >40 dB in the output fibers, V, = 10 Volts, 3-dB bandwidth of 1 GHz, and intensity modulation less than 0.1% over ± 2 V?.
