Multiple wavelength: nonlinear optical processing in fiber

Nonlinear fiber based devices and in particular multiple wavelength nonlinear fiber devices are reviewed. A number of important devices can be fabricated using various lengths of fiber in combination with the appropriate input signals and pumps of sufficient power. The low loss fiber provides a unique medium whereby these important nonlinear processes can occur. These processes include among others Brillouin scattering, Raman scattering, parametric amplification, wavelength conversation, self phase modulation, and four wave mixing. Possible applications for these processes include high bit rate dynamic dispersion compensation, 2R regeneration, the continuum generation and nonlinear polarization dynamics.
