Abstract
A high performance integrated optical circuit for a broad range of fiber optic gyro applications at 1.3 μm is reported. The chip integrates four directional couplers and six phase modulators to perform fiber loop coupling, bias and serrodyne phase modulation, and on chip interferometric serrodyne phase detection. The chip was fabricated by the annealed-proton-exchange method in LiNbO3 yielding a strongly polarized guided circuit with a polarization extinction ratio of at least 60 dB. The halfwave voltages of the phase modulators were 3.5 V and 5.5 V, the 50% splitting and 10% tapping of directional couplers were well within the design specifications.
