Abstract: Optical fiber composed of a glass doped with at least laser-active ions of an element from the rare earths. An optical fiber of glass, preferably a HMF glass, doped with Tm.sup.3+ is operated at 1.48 .mu.m as a fiber laser or amplifier on the laser transition .sup.3 F.sub.4 -.sup.3 H.sub.4. Since this thereby involves a self-saturating transition, the terminal level is emptied in accelerated fashion for a continuous wave mode by co-doping with de-activators, preferably Ho.sup.3+, Tb.sup.3+, Eu.sup.3+ and/or Pr.sup.3+ ions. The pump light wavelength can be selected from the wavelength range from 700 through 890 nm of GaAlAs emission. The optical fiber can be used in optical amplifiers or fiber amplifiers.

Abstract: The present invention embraces an amplifying optical fiber having a central core adapted to convey and amplify an optical signal and a cladding that surrounds the central core to confine the optical signal conveyed in the central core. The central core is formed of a core matrix in which nanoparticles are present. The nanoparticles themselves include a nanoparticle matrix and rare-earth-dopant elements. The core matrix may also include one or more additional dopants (i.e., in addition to nanoparticles). The amplifying optical fiber possesses a small numerical aperture and is suitable for use in high-pump-power applications without a degraded gain shape.

Abstract: A device amplifies light at wavelengths in the vicinity of 1420-1530 nm, using thulium doped silica-based optical fiber. This wavelength band is of interest as it falls in the low-loss optical fiber telecommunications window, and is somewhat shorter in wavelength than the currently standard erbium doped silica fiber amplifier. The device thus extends the band of wavelengths which can be supported for long-distance telecommunications. The additional wavelength band allows the data transmission rate to be substantially increased via wavelength division multiplexing (WDM), with minimal modification to the standard equipment currently used for WDM systems. The host glass is directly compatible with standard silica-based telecommunications fiber. The invention also enables modified silicate based amplifiers and lasers on a variety of alternative transitions. Specifically, an S-band thulium doped fiber amplifier (TDFA) using a true silicate fiber host is described.
