  • Precisely wavelength-tunable and wavelength-switchable narrow linewidth lasers
    Patent number: 6570893
    Abstract: Continuously tunable and precisely wavelength-switchable fiber lasers combine fiber Bragg gratings and the transmissive filtering properties of high finesse fiber Fabry-Perot filters. This laser arrangement adapts to multiple wavelength ranges based on the selections of fiber Bragg grating and gain medium and their arrangement to create a wavelength-modulatable and simultaneously rapidly wavelength-switchable narrow linewidth all-fiber laser design. This laser arrangement further results in narrow-linewidth outputs with fast switching speeds between the selected wavelengths.
    Type: Grant
    Filed: November 24, 1999
    Date of Patent: May 27, 2003
    Assignee: Science & Technology Corporation @ UNM
