  • High-power cladding-pumped broadband fiber source and amplifier
    Patent number: 6263003
    Abstract: A very high power fiber light source can be realized by using a high concentration of doping and by pumping the cladding of the doped fiber. The light that enters the cladding will then enter the core and amplified spontaneous emission will result. With this arrangement, higher power, a broader emission spectrum, and low radiation sensitivity can be achieved. These devices can also be configured as amplifiers.

  • 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.
