  • Title: Polarization independent wavelength conversion in fibers using incoherent pumps.
    Author: Tian Y, Dong P, Yang C.
    Journal: Opt Express; 2008 Apr 14; 16(8):5493-8. PubMed ID: 18542652.
    Abstract:
    We report polarization independent wavelength conversion based on one-pump fiber optical parametric amplifiers. A spectrum-sliced amplified spontaneous emission (ASE) light source is used to provide a non-polarized pump. The signal is coherent lights coming from a tunable laser. When adjusting the polarization of the signal using a polarization controller, the variation of wavelength conversion efficiency is less than 0.2 dB. We use the vector theory of four-wave mixing to analyze the polarization independent nature of wavelength conversion by using randomly polarized pumps.
