Abstract

Nonlinear effects in fibers with partially coherent pumps have attracted a great interest in view of their potential for polarization insensitive wavelength conversion and the increased resilience to Stimulated Brillouin Scattering [1]. In this work we experimentally study the problem of non-degenerate four-wave-mixing (FWM) by using a pair of partially coherent pumps, and focus our attention on a specific type of FWM, which is generally called “Bragg-Scattering” (BS-FWM). This kind of FWM has attracted a renewed interest because of its intrinsically low-noise nature which makes it potentially applicable for light-by-light manipulation even for very faint signals such as quantum keys [2].

Detrimental effects in four wave mixing

Karsten K. Rottwitt, Thjalfe Ulvenberg, Lars Søgaard Rishøj +2 more

Four wave mixing (FWM) holds great promise as a tool to perform signal processing of classical light as well as of quantum states. However, typically FWM require use of high power pumps and as a consequence, the FWM process is accompanied by spontaneous Raman scattering as well as spontaneous FWM. In addition, FWM is also very sensitive to changes in the phase matching along propagation, caused by fluctuations in the core geometry of the fiber. In this work, we review recent progress in predicting and measuring the conversion efficiency and noise figure of wavelength conversion using FWM and we show consequences due fluctuations in the core geometry.

Translation of quantum states by four-wave mixing in fibers

Colin J. McKinstrie, J.D. Harvey, Stojan Radic +1 more

Optical frequency conversion by four-wave mixing (Bragg scattering) in a fiber is considered. If the frequencies and polarizations of the waves are chosen judiciously, Bragg scattering enables the translation of individual and entangled states, without the noise pollution associated with parametric amplification (modulation instability or phase conjugation), and with reduced noise pollution associated with stimulated Raman scattering.

Quantum state preserving frequency conversion using four-wave mixing in optical fibers: The impact of Raman scattering

Karsten K. Rottwitt, Mathias Linde Holst Korsgaard, Jacob G. Koefoed

Using a theoretical model, we investigate the impact due to Raman scattering on frequency conversion obtained via Bragg scattering four-wave mixing in optical fibers. We predict the second order correlation functions and show that by using a specific polarization configuration of the pumps and signal it is possible to significantly mitigate the impact of Raman scattering by reducing the second order correlation function by at least a factor of two.
