Four-wave mixing in the diamond configuration in an …

Received 29 December 2008; published 12 March 2009 We present measurements of the resonance structure for nondegenerate four-wave mixing 4WM in the diamond configuration in a warm atomic vapor of rubidium. We show that a narrow sub-Doppler feature exists and can be understood as a result of velocity-class selection.

Quantum frequency conversion (QFC), a critical technology in photonic quantum information science, requires that the quantum characteristics of the frequency-converted photon must be the same as the input photon except for the color. In nonlinear optics, the wave mixing effect far away from the resonance condition is often used to realize QFC because it can prevent the vacuum field …

Linking enhanced turbulence to the internal wave field has been a major advance (Saggio and Imberger 1998; MacIntyre et al. 1999; Rudnick et al. 2003). It is now well established that considerable turbulence occurs near lateral boundaries. For instance, recent oceanographic

We report experimental observation of slow or fast light in configuration of counterpropagating saturating and probe waves in erbium-doped fibers with saturable absorption. The delayed or accelerated probe light propagation is shown to be associated with two-wave mixing (TWM) between these two waves via dynamic population grating. As compared with recording at 1526 nm from the central region ...

Four Wave Mixing - an overview | ScienceDirect Topics

Four-wave mixing, a nonlinear phenomenon discussed in Chapter 10, is known to affect the SRS in any medium [6]. Its impact on the SRS process in optical fibers has been studied extensively [24–32]. This subsection describes the relevant features qualitatively. To understand how four-wave mixing can influence SRS, it is useful to reconsider ...

Invited Article: Enhanced four-wave mixing in waveguides ...

We demonstrate enhanced four-wave mixing (FWM) in doped silica waveguides integrated with graphene oxide (GO) layers. Owing to strong mode overlap between the integrated waveguides and GO films that have a high Kerr nonlinearity and low loss, the FWM efficiency of the hybrid integrated waveguides is significantly improved.

Spatial displacements of the probe and generated four-wave mixing beams are observed in a three-level V-type, as well as a two-level atomic system near resonance. The observed spatial shift curves reflect the typical enhanced cross-Kerr nonlinear dispersion properties in the electromagnetically induced transparency (EIT) systems. The spatial beam displacements are controlled by the strong ...

We consider the dynamical degenerate four-wave mixing (FWM) model in a cubic nonlinear medium including both the time relaxation of the induced nonlinearity and the nonlocal coupling. The initial ten-dimensional FWM system can be rewritten as a three-variable intrinsic system (namely the intensity pattern, the amplitude of the nonlinearity and the total net gain) which is very close to the ...

We demonstrate efficient, low power, continuous-wave four-wave mixing in the C-band, using a high index doped silica glass micro ring resonator having a Q-factor of 1.2 million. A record high conversion efficiency for this kind of device is achieved over a bandwidth of 20nm. We show theoretically that the characteristic low dispersion enables phase-matching over a bandwidth > 160nm.
