Degenerate Four Wave Mixing in Photonic Crystal Fibers
نویسنده
چکیده
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 that the influence of FWM can be reduced by irregular channel spacing. We use three wavelengths in the calculations (580, 780, and 1040nm) which are the zero dispersion wavelengths, all the results reported in this work are simulated using MATLAB 7. :ةــــــصلاخلا ددزا لا ام دار زف نات ةاسارد مات ثافم ةاحروةبلا ةفاوايلا لتافليا ياف تاجوم عبرأ جمد ةسارد مت ,ثحبلا اذه يف ةاسارد مات دلذار و تاجوملا جامد د تافر اةع مذخ سملا ففةلا لوط و تجوملا روط قبتطت مذع , تجوملا فب دصتفلا لا هذه م ةجتتنلا ةجوملا ددزت يف زفغ لا زظنب ذخيا عم دزش نملا ةجومةل و خيلا رذصمل يجوملا لوطلا م در عم ةفنق ( يه و تبتسحلا يف ةفجوم لاوطا ة لا ماذخ سا مت،ت ش لا زف نت رتب علاا 580,780, 1040nm يف ة بثملا جات نلا در ،) ( بلاتتملا دترتحم جمتنزب ماذخ ستب تمت ثحبلا اذه 7 )

Intermodal and cross-polarization four-wave mixing in large-core hybrid photonic crystal fibers.
Degenerate four-wave mixing is considered in large mode area hybrid photonic crystal fibers, combining photonic bandgap guidance and index guidance. Co- and orthogonally polarized pump, signal and idler fields are considered numerically by calculating the parametric gain and experimentally by spontaneous degenerate four-wave mixing. Intermodal and birefringence assisted intramodal phase matchin...
متن کاملFrequency-dissymmetric parametric sideband generation in a microstructured fiber
We experimentally demonstrate the nonlinear generation of frequency-dissymmetric sidebands by injecting picosecond pump pulses inside the fundamental mode of a silica-core photonic crystal fiber in its normal dispersion regime. A systematic analysis highlights the fact that this phenomenon is based on the combination of the two major nonlinear effects occurring inside the fiber: self-phase modu...
متن کاملDegenerate four waves mixing in multilayer nanoshell
We will present a detailed investigation of intersubband transitions process in core-multi shells quantum dots. The confined wave functions and eigenenergies of electrons in quantum dots have been calculated under the effective-mass approximation by solving a three-dimensional Schrodinger equation. Excellent dependence is found between size effects, time relaxation and degenerate four wave mixi...

متن کاملInvestigation of Scalar Modulation Instability in the Presence of Raman Scattering in Photonic Crystal Fibers
In this paper, by including Raman scattering in the coupled-mode equations, the scalar modulation instability in photonic crystal fibers is investigated. The evolution of the pump, Stokes and anti-Stokes waves along the fiber as well as the conversion efficiency for two cases, with and without Raman effect, are studied. The effect of anti-Stokes seed and the pump depletion on the evolution of S...

We present an analytical study of four-wave mixing instabilities in tapered fibers and photonic crystal fibers. Our approach avoids the use of Taylor expansion for the linear susceptibility and the slowly-varying envelope approximation. This allows us to describe the generation of sidebands strongly detuned from the pump wave with simultaneous account for the entire dispersion characteristic of...
