Ti:LiNbO(3) Components for a Fiber Gyroscope

Integrated optics will play a major role in the next generation of fiber gyros since the potential exists fpr mass producing low cost integrated gyro front-end circuits. All the necessary components (phase modulators, polarizers, and power splitters) have been demonstrated with Ti:LiNb0(3) waveguide technology. An attractive alternative of combining the 3 dB splitter and polarizer functions in a 3x3 directional coupler is presented.
