  • Waveguide-based optical interferometer
    Patent number: 7003186
    Abstract: Techniques for measuring spatial locations. An apparatus for measuring spatial locations includes a first object at a first location, a second object at a second location, and a waveguide-based interferometer coupled between the first object and the second object. The waveguide-based interferometer includes a waveguide material. The waveguide material is adapted to carry at least a reference beam and a measurement beam. The reference beam traverses a first path defined within the waveguide material. The measurement beam traverses a second path defined within the waveguide material and a third path defined outside of the waveguide material. The third path is related to at least one of the first location and the second location.

  • Robust heterodyne interferometer optical gauge
    Patent number: 6947621
    Abstract: A method for performing optical signal and beam distribution in a heterodyne interferometer. A planar lightwave circuit is provided including a plurality of waveguide optical transmission elements and an input coupler and an output coupler arranged along the optical transmission elements. Optical pathlengths of the transmission elements are matched between the input coupler and the output coupler to compensate for thermal effects. Reference and measurement optical phases are determined employing the input coupler and the output coupler.
