In the perturbation regime, the abundance of different spectroscopic methods that utilize spatial phase matching such as transient grating, photon echo and other multi-wave mixing techniques have significant differences and benefits for approaching matter information with different detection windows.

Ultrafast nonlinear spectroscopy, which records transient wave-mixing signals in a medium, is a powerful tool to access microscopic information using light sources in the radio-frequency and optical regimes.

The seasonal cycle is imposed on simple ordinary differential equation models for each physical regime either as a seasonal ocean– atmosphere coupling strength obtained from the model of Zebiak and Cane or as a climatological seasonal upwelling.

This Letter reports the first experimental demonstration of progressive chaos development through four-wave mixing of spin wave amplified harmonics in magnonic active-ring oscillators. We find that the route to chaos represents a sequence of quasiperiodic regimes of oscillations and ultimately yields formation of a 3D torus in the phase space.

Comparative analysis of four-wave mixing of optical pulses in slow- and fast-light regimes of a silicon photonic crystal waveguide. Lavdas S, Panoiu NC. We present an in-depth study of four-wave mixing (FWM) of optical pulses in silicon photonic crystal waveguides. Our analysis is based on a rigorous model that includes all relevant linear and ...

A method of generating a non-zero frequency spacing between two laser diodes, using four-wave mixing, mediated by injection-locking in order to potentially realise THz radiation is presented. Four distinct regimes of operation are observed, including a periodic response, where the oscillations are simply related to the relaxation oscillations of the system; a periodic response with multiple ...

Graphene is one the most promising two-dimensional materials for functional electromagnetic components. Harnessing graphene's high third-order nonlinearity, a standing-wave resonant system is proposed that realizes low-power and high-conversion-efficiency degenerate four-wave mixing in the THz regime. The proposed system is analyzed in depth, using a recently developed nonlinear …

Four-wave mixing (FWM) is a nonlinear optical process that coherently combines three waves to produce a fourth one, and is used in many areas of physics. In atomic physics FWM is utilized to study spectroscopic and quantum optics processes [1–6]. It can generate specific frequencies not available with direct electromagnetic sources, and has

Four-wave mixing (FWM) is an intermodulation phenomenon in nonlinear optics, whereby interactions between two or three wavelengths produce two or one new wavelengths. It is similar to the third-order intercept point in electrical systems. Four-wave mixing can be compared to the intermodulation distortion in standard electrical systems. It is a parametric nonlinear process, in that the energy ...

Nonlinear optics (NLO) is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the polarization density P responds non-linearly to the electric field E of the light. The non-linearity is typically observed only at very high light intensities (values of atomic electric fields, typically 10 8 V/m) such as those provided by lasers.

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 ...

Flow Regimes. For low Reynolds numbers the behavior of a fluid depends mostly on its viscosity and the flow is steady, smooth, viscous, or laminar and n = 1. For high Reynolds numbers the momentum of the fluid determines its behavior more than the viscosity and the flow is unsteady, churning, roiling, or turbulent and n = 2.

Four-wave mixing (FWM) of optical fields has been extensively used in quantum information processing, sensing, and memories. It also forms a basis for nonlinear spectroscopies such as transient grating, stimulated Raman, and photon echo where phase matching is used to select desired components of the third-order response of matter.
