Stimulated Brillouin scattering inside an optical fiber

  1. Jan 23, 2014 #1
    Hello everyone
    I need some one once and for all to give me the steps to have a clear step by step idea about the stimulated Brillouin scattering inside an optical fiber please and thank you

    Here are two papers that may help:

    lol Bobby,
    that second one of yours I had already posted SNAP :wink:

    davenn: Yes, If I wanted to study that subject, the "corning" paper looked like a good place to start.

    Great minds think alike.

    I want to know how exactly does it work in the fiber by using SBS and FWM because once I understand those I can start with my project

    Thank you my friend do u have any papers concerning FWM that would be great also thank you

    Thank you so much one more thing do you have any papers for FWM that would be awesome because I still don't have access to the uni thank yoi

    Eahaidar,

    You have asked about “FWM”. This abbreviation might stand for “Four Wave Mixing”, or something else.

    But I guess you meant “FWHM”. This abbreviation stands for “full width at half maximum” and appears in Section Two of the paper “Stimulated Brillouin Scattering: An Overview of Measurements, System Impairments, and Applications” referenced above.

    If my guess is correct, you need to learn exactly what the term means, because it is commonly used in many areas of science. One place to begin is Wikipedia:

    “Full width at half maximum (FWHM) is an expression of the extent of a function, given by the difference between the two extreme values of the independent variable at which the dependent variable is equal to half of its maximum value.
    FWHM is applied to such phenomena as the duration of pulse waveforms and the spectral width of sources used for optical communications...”
    http://en.wikipedia.org/wiki/Full_width_at_half_maximum

    These two sites also explain “FWHM”:

    http://ned.ipac.caltech.edu/level5/Leo/Stats2_3.html


    Finally, here’s another paper that gives an excellent overview of your topic:

    "NONLINEAR SCATTERING EFFECTS IN OPTICAL FIBERS
    S. P. Singh, R. Gangwar, and N. Singh
    Department of Electronics and Communication
    University of Allahabad
    Allahabad-211002, India
    Abstract—The nonlinear scattering effects in optical fiber occur due
    to inelastic-scattering of a photon to a lower energy photon. This
    paper describes stimulated Brillouin scattering and stimulated Raman
    scattering processes. Their thresholds, reduction in power penalty and
    applications along with comparative study of these effects are also
    presented."

    Cheers, Bobbywhy

    Hey bobby
    Thank you for the reply
    I am asking about four wave mixing and the reason that I will work on fixing the phase matching of FWM using gain of SBS inside a chalcogenide chip that so if you have papers about then that would be great anything would help thank you again
