Patent Number Title Of Patent Date Issued
5327213 Configuration control of mode coupling errors July 5, 1994
An optical fiber rotation sensor having configurations thereof chosen with respect to the source autocorrelation. Both amplitude related and intensity related phase errors due to polarization mode coupling can be eliminated or reduced economically.
5289258 Fiber optic gyroscope modulation error reduction February 22, 1994
An error control arrangement for an optical fiber rotation sensor having electromagnetic waves propagating in opposite directions passing through a bias optical phase modulator operated by a phase modulation generator both of which can contribute second harmonic distortion resulting in e
5022732 Fiber optic intermode coupling single sideband frequency shifter June 11, 1991
An optical fiber is subjected to a series of traveling flexural waves propagating along a length of the fiber. At least a portion of an optical signal propagating within the optical fiber in a first propagation mode is coupled to a second propagation mode. The optical signal in the secon
4915468 Apparatus using two-mode optical waveguide with non-circular core April 10, 1990
An apparatus utilizes a two-mode optical waveguide with a non-circular core to provide stable spatial intensity patterns in both propagation modes for light propagating therein. The light has a wavelength, and the non-circular core has cross-sectional dimensions selected such that (1)
