Ultra-Low Loss Large Area Waveguide Coils for Integrated Optical Gyroscopes

Abstract

We discuss the design, fabrication, and measurement of a large area stitched gyroscopic coil, reporting waveguide loss, including 100 stitches over 3 m, of 0.78 dB/m and crossing loss of 0.0156 dB/crossing for a predicted ARW of 69° /hr/√(Hz).
