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. |

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 |

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 |

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) |
