Doped Fiber

Some articles on doped fiber, fiber, doped, fibers:

Erbium-doped Waveguide Amplifier - Laser Amplifiers - Erbium-doped Fiber Amplifiers
... The erbium-doped fiber amplifier (EDFA) is the most deployed fiber amplifier as its amplification window coincides with the third transmission window of silica-based ... difference between C- and L-band amplifiers is that a longer length of doped fiber is used in L-band amplifiers ... The longer length of fiber allows a lower inversion level to be used, thereby giving at longer wavelengths (due to the band-structure of Erbium in silica) while still providing a useful amount of gain ...
Lanthanide - Applications
... Erbium-doped fiber amplifiers are significant devices in optical-fiber communication systems ... Most lanthanides are widely used in lasers, and as (co-)dopants in doped-fiber optical amplifiers for example, in Er-doped fiber amplifiers, which are used as repeaters ...
Erbium-doped Waveguide Amplifier - Laser Amplifiers - Doped Fiber Amplifiers For Other Wavelength Ranges
... Thulium doped fiber amplifiers have been used in the S-band (1450–1490 nm) and Praseodymium doped amplifiers in the 1300 nm region ... However, Ytterbium doped fiber lasers and amplifiers, operating near 1 micrometre wavelength, have many applications in industrial processing of materials, as these devices can be made ...
Fiber Optic - Applications - Other Uses of Optical Fibers
... Fibers are widely used in illumination applications ... In some buildings, optical fibers route sunlight from the roof to other parts of the building (see nonimaging optics) ... Optical fiber illumination is also used for decorative applications, including signs, art, toys and artificial Christmas trees ...

Famous quotes containing the word fiber:

    I taught school in the early days of my manhood and I think I know something about mothers. There is a thread of aspiration that runs strong in them. It is the fiber that has formed the most unselfish creatures who inhabit this earth. They want three things only; for their children to be fed, to be healthy, and to make the most of themselves.
    Lyndon Baines Johnson (1908–1973)
