    Abstract: An optical amplifier comprises a trivalent thulium-doped optical fiber; a first pump light emitting device optically coupled to the fiber for generating a primary pump source at a first wavelength, and a second pump light emitting device optically coupled to the fiber for generating a secondary pump source at a second wavelength. In a preferred aspect of the present invention, the amplifier also includes a third (auxiliary) pump light emitting device optically coupled to the fiber for generating a third pump source at a third wavelength. Each of the amplification signals comprise at least one pre-selected wavelength. The first amplification signal has a wavelength pre-selected to provide a reduced noise figure for the amplifier. The second amplification signal has a wavelength pre-selected to increase the optical efficiency of the amplifier. The third amplification signal can have a wavelength pre-selected to populate the 3F4 energy level of the fiber, and to minimize depletion of the 3H6 ground state.

    Abstract: A glass-ceramic rare earth doped fiber comprises a plurality of crystallites, wherein at least 90% of the rare earth dopant is situated within said crystallites. The stimulated emission and absorption line shapes of the rare earth doped glass-ceramic fiber is narrower than that stimulated emission and absorption line shapes of the precursor rare earth doped glass. This is indication of the reduction in the inhomogenous broadening of glass-ceramic fibers compared to glass fibers. An embodiment of an optical amplifier includes: an input port; a length of glass-ceramic rare earth doped fiber, the glass-ceramic fiber being operatively coupled to the input port and including a plurality of crystallites; at least one optical pump coupled to this glass-ceramic fiber; an output port providing an amplified optical signal; and at least one optical component situated between the input port and the output port.

    Abstract: The dual wavelength pumping scheme controls the relative population of the termination state vis-a-vis the metastable state. Praseodymium doped chalcogenide glass and a variety of thulium doped glasses are described as examples. The relative pump powers or wavelengths may be adjusted to control the gain spectrum of the amplifier, making the amplifier useful in a variety of different optical systems including wavelength division multiplexed systems.

In a preferred aspect of the present invention, the amplifier also includes a third (auxiliary) pump light emitting device (130) optically coupled to the fiber (120) for generating a third pump source at a third wavelength. Each of the amplification signals comprise at least one pre-selected wavelength. The first amplification signal has a wavelength pre-selected to provide a reduced noise figure for the amplifier. The second amplification signal has a wavelength pre-selected to increase the optical efficiency of the amplifier. The third amplification signal can have a wavelength pre-selected to populate the 3F4 energy level of the fiber, and to minimize depletion of the 3H6 ground state.
