Bragg scattering in a positive ß4 fiber.

The phase-matching curves for the four-wave mixing effect of Bragg scattering in two fibers with opposite sign ß(4) dispersion coefficients have been measured experimentally. The measured phase-matching curves are in good agreement with theoretical expectations, and their dependence on several key parameters has been determined.

180-nm wavelength conversion based on Bragg scattering in an optical fiber.

Efficient, wideband and tunable optical wavelength conversion over 180 nm by four-wave mixing (Bragg scattering) in a fiber is demonstrated experimentally. This process has the potential to translate optical data (states of light) without the noise pollution associated with parametric amplification and spontaneous Raman scattering.
