<p>An integrated optics chip (10) which is the central module for an inteferometric gyro (45). The configuration performs bias reduction, noise reduction, and improves scale factor linearity and repeatability. The chip (10) is fabricated in an electro-optic material using conventional waveguide fabrication techniques, for example, titanium infusion into LiNbO3. Light propagating into the chip from a source is split equally between two legs which are coupled to optical fibers (43, 44). Similarly light propagating in the legs may be coupled together and the combined signal coupled into an optical fiber (42).</p> |
