Abstract
Bias drift error caused by optical back-reflections of clockwise and counterclockwise rotating beams in an integrated optic fiber-optic gyro and originating at a chip/coil interface are reduced by using a chip architecture designed so that the pathlength over which one of the beams is transmitted before being coupled into a fiber-optic coil and the pathlength over which the other beam is transmitted are different. The difference is provided by bending a waveguide transmitting the one beam, with said bending being enhanced by the application of the Titanium Indiffused Proton Exchange process.
