Ph. D Thesis

I completed my Ph.D Thesis in the P. M. Duffieux Optics Laboratory at the University of Franche-Comté from 1995 to 1999 and I defended it on january, 20 1999 with the following title: "Parametric amplication and frequency conversion, Frequency shift and Raman suppression in optical fibers".

During my Ph. D, I investigated both theoretically and experimentally fundamental aspects of nonlinear optical effects occurring in optical fibers such as self- and cross-phase modulation, optical solitons, parametric amplification, modulation instability and stimulated Raman scattering. I demonstrated in particular two novel techniques for efficient stimulated Raman scattering suppression using two pump lasers and Raman-assisted far-detuned parametric wavelength conversion in optical fibers. I also reported the observation of parametric amplification, degenerate cross-phase modulation, and vector solitons in highly birefringent optical fibers.
