It is apparent from the Fig. The model is characterized on the basis of rate equations. They differ in various respects from rare-earth-doped amplifiers, and are discussed in the article on Raman amplifiers. The variation of gain with input pump power mW observed for various fiber lengths m. Most fiber amplifiers are not made of polarization-maintaining fibersso they do not preserve the polarization state of the input. In some cases, however, polarization hole burning can cause problems. The gain achievable is often limited by ASE see below. The yellow color is used to highlight the display blocks. The effect of the nonlinearity can be reduced e.

    Gain flattened C-band erbium-doped fiber amplifier (EDFA) is demonstrated 23 FebAccepted 30 JunPublished online: 16 Aug The amplifier uses a 9 m long erbium-doped fiber (EDF) with erbium ion.
    Giles and E. Forward ASE is partially reabsorbed before it reaches the right end. The amplified spontaneous emission power travels round trip in the EDFA.

    A technique for radically reducing nonlinear effects is chirped-pulse amplificationwhere pulses are strongly dispersively stretched before entering the amplifier and subsequently compressed again. Paschotta, tutorial on " Fiber Amplifiers ". They differ in various respects from rare-earth-doped amplifiers, and are discussed in the article on Raman amplifiers.

    These properties of EDFA are very decisive for its deployment in local area network. However, the simulator can be extended for multiple signal sources using the switches.

    An accurate model with supporting mathematics is elaborated and the results are presented graphically. Fermann, A.

    For amplifying the output of a mode-locked laserthe gain saturation is normally the same as for a continuous-wave laser with the same average power.

    Paschotta, tutorial on " Modeling of Fiber Amplifiers and Lasers ". A variable pump power can also lead to temperature-dependent heating which translates into phase noise.

    Even in simple cases, relatively complex behavior can result. Quantum Electron. ASE itself may be utilized for superluminescent sources with very low temporal coherenceas required e.

    Fiber amplifiers for the second telecom window around 1. One recognizes that the ASE in the nm region is quite similar in both directions, whereas strong nm ASE occurs only in backward direction. Due to high pump depletion beyond the effective length of fiber, the gain experienced by the amplifier begins to decrease after a saturation level. Forward Raman amplifier suffers pulse smearing and data loss due to the pulse walk-off effect in DWDM amplification systems.

    1. Note: the article keyword search field and some other of the site's functionality would require Javascript, which however is turned off in your browser.

    2. The noise figure substantially increases while input pump power keeps on increasing from 10 to 30 mw along the fiber length.

    3. Combined thulium—erbium amplifiers can thus provide optical amplification in a very wide wavelength range. It is apparent that ASE power enhance with length of fiber because of the gain delivered by EDFA and achieves the maximum quantity for extra pump power.
