Solitons vs light wave.

  1. Dec 18, 2009 #1
    "Solitary waves that run a long distance without losing their shape or dying out are a special class of waves called solitons."

    Such examples as in light waves in optical fibers, vibration frequencies within crystalline structures, and B.E. condensates.

    My question is does regular light wave count as a soliton? Does light ever slow down or run out so to speak?

    If you emit a spherical pulse of light it will decay as 1/r² so it will decay and not be a soliton. You might count a well-focused laser pulse as a soliton.
