Continuous backward-wave generation by degenerate four-wave mixing in optical fibers.
The generation of time-reversed wavefronts via degenerate four-wave mixing has been the topic of many recent theoretical' and experimental2 investigations. Potential applications of this interaction include active filters3 and real-time holographic devices.4' 5 Being a third-order nonlinear optical process, this phenomenon generally requires high-laser-beam intensities and long interaction leng...
متن کاملPhoton-pair generation by four-wave mixing in optical fibers.
We present a theory to quantify a fundamental limit on correlated photon pairs generated through four-wave mixing inside optical fibers in the presence of spontaneous Raman scattering (SpRS). Our theory is able to explain current experimental data. We show that if correlated photon pairs are generated with polarization orthogonal to the pump the effect of SpRS is significantly reduced over a br...
متن کاملDegenerate Four Wave Mixing in Photonic Crystal Fibers
In this study, Four Wave Mixing (FWM) characteristics in photonic crystal fibers are investigated. The effect of channel spacing, phase mismatching, and fiber length on FWM efficiency have been studied. The variation of idler frequency which obtained by this technique with pumping and signal wavelengths has been discussed. The effect of fiber dispersion has been taken into account; we obtain th...
متن کاملDegenerate four-wave mixing in noncentrosymmetric materials
This work treats degenerate four-wave mixing ~DFWM! in noncentrosymmetric materials, taking into full account the fact that the DFWM signal arises from third-order nonlinear optical effects as well as from two distinct combinations of second-order effects: second-harmonic generation plus difference frequency generation and optical rectification plus Pockels effect. Because of these second order...
متن کاملFour-Wave Mixing in Optical Fibers and Its Applications
When a high-power optical signal is launched into a fiber, the linearity of the optical response is lost. One such nonlinear effect, which is due to the third-order electric susceptibility is called the optical Kerr effect. 1), 2) Four-wave mixing (FWM) is a type of optical Kerr effect, and occurs when light of two or more different wavelengths is launched into a fiber. Generally speaking FWM o...
