Paper Abstract

For constructing a quadrature phase interferometer for optical current sensors, we integrated various optical components on a single polymeric waveguide chip. To obtain stable output in quadrature interferometer, it is important to remove the scattered light inside the planar waveguide of integrated optics. In this work, we analyzed the mechanism of optical interference due to the radiated light, and improved the structure of optical waveguide device . After the improvement of waveguide structure, the sensor output signal was maintained within ±0.5% error range regardless of its operating point drift.
