Parametric and Raman amplification in photonic crystal fiber

Stefan W. Wabnitz, Guy Millot, Stéphane Pitois +2 more

We study the interplay between parametric and Raman gain in photonic crystal fibers by taking into account the vector nature of the electric field, the fiber frequency dependent birefringence, the Kerr nonlinear coefficient, the Raman gain profile and chromatic dispersion. In particular, we show that an accurate representation of the frequency dependence of the nonlinear and dispersive properties of a photonic crystal fiber is essential for correctly describing the overall gain profile for a probe signal at large frequency detuning from a continuous wave or pulsed pump. For example, we found that fourth and higher order dispersion have a striking influence on the spectrum of modulation polarization instability gain in both the high and low birefringence regime, in that the vector parametric gain is suppressed above a critical level of linear birefringence. We validated the theory by experimental observations of vector parametric amplification in high birefringence holey fiber with triple defects.We study the interplay between parametric and Raman gain in photonic crystal fibers by taking into account the vector nature of the electric field, the fiber frequency dependent birefringence, the Kerr nonlinear coefficient, the Raman gain profile and chromatic dispersion.

4bits all-optical quantization based on the Raman self-frequency shift and spectral compression

Rui Liang, Xiaojun Zhou, Zhiyao Zhang +1 more

We numerically analyze the all-optical quantization based on the Raman self-frequency shift in a photonic crystal fiber. Resolution of 4bits can be realized with increasing a dispersion-decreasing fiber to compress the shifted spectrum.

Coherent intramodal Raman gain suppression at high pump intensities in gas-filled photonic crystal fibres

Pooria Hosseini, Manoj Kumar Mridha, David Novoa +2 more

Stimulated Raman scattering is coherently suppressed if the rate of phonon creation is exactly balanced by the rate of phonon annihilation, a prediction first made by Bloembergen and Shen in 1964 [1]. Viewed classically, this occurs when the fringe patterns created by the interference of pump-Stokes and pump-anti-Stokes signals cancel each other out. It has been recently shown that gas-filled hollow-core photonic crystal fiber (HC-PCF), pumped in the vicinity of the zero-dispersion point (ZDP), is an ideal vehicle for observing gain suppression. The ultralong path-lengths and the well-controlled dispersion permit dramatic suppression of the effective intramodal Raman gain for the fundamental core mode [2, 3], resulting in strong enhancement of intermodal scattering from the pump to a Stokes signal in a higher-order core mode.Stimulated Raman scattering is coherently suppressed if the rate of phonon creation is exactly balanced by the rate of phonon annihilation, a prediction first made by Bloembergen and Shen in 1964 [1].
