  • Method for controlling the wavelength of an optical fiber-based light source
    Patent number: 6327277
    Abstract: The output wavelength of a laser-diode pumped fiber source can be stabilized at its minimum value irrespective of temperature and the age of the laser diode by the seeking the minimum output wavelength of the fiber source. By introducing a dither on the temperature of the pump laser diode, a measurement feedback loop can be used to determine the optimal value of the temperature. Once determined, the temperature is used to fix the wavelength of the source.

  • Optical signal noise reduction for fiber optic gyroscopses
    Patent number: 5898496
    Abstract: The RIN (random intensity noise) component of the random walk error of a fiber optic gyroscope can be reduced by utilizing an unpolarized light signal during processing. By depolarizing the light wave modulated by the fiber optic sensing coil or combining it with the unmodulated light wave of orthogonal polarization, a 3 db reduction in RIN can be achieved.
