“…Also recently, Graphene (Gr) as a new nonlinear material [8][9][10][11][12] with strong refractive and absorption nonlinearity has been attracted a great deal of attentions for designing new nonlinear devices. However, up to now, mainly the saturation absorption effect in Gr and its derivatives (such as Gr oxide) that is arisen from Gr absorption nonlinearity (imaginary part of nonlinear refractive index) is used for designing nonlinear devices such as Q-switches [13,14] or optical limiters [15,16]. This is due to the fact that Gr also has relatively large absorption (2.3%) in comparison with its low thickness (0.34nm).…”

Abstract.Scientists are working to realize all-optical signal processing and computation in which digital all-optical integrated circuits are required, while all-optical amplitude limiter is a basic element for such circuits. We demonstrate an all-optical amplitude limiter with a single nano-scale Graphene layer inside a multilayer waveguide based on a novel mechanism that uses input-wave intensity-dependent scattering objects, side-way waveguide of Gr and photonic bandgap-edge resonance effects to enhance the nonlinear effects. It is shown that the light transmitted through the proposed structure in the vertical direction has an upper limit for different input intensity of light, i.e., it operates as a limiter. This is realized by scattering light sideway to propagate along the horizontal waveguide.

“…Its linear dispersion relation between energy and crystal momentum results in remarkable material parameters and makes it a star contender for lots of applications, especially for electronic [14][15][16][17], photonic [18,19], and optoelectronic applications [20][21][22][23][24]. With zero bandgap, graphene can absorb electromagnetic radiation ranging from far-infrared to UV light [25].…”

Optical receivers with potentially high operation bandwidth and low cost have received considerable interest due to rapidly growing data traffic and potential Tb/s optical interconnect requirements. Experimental realization of 65 GHz optical signal detection and 262 GHz intrinsic operation speed reveals the significance role of graphene photodetectors (PDs) in optical interconnect domains. In this work, a novel complementary metal oxide semiconductor post-backend process has been developed for integrating graphene PDs onto silicon integrated circuit chips. A prototype monolithic optoelectronic integrated optical receiver has been successfully demonstrated for the first time. Moreover, this is a firstly reported broadband optical receiver benefiting from natural broadband light absorption features of graphene material. This work is a perfect exhibition of the concept of monolithic optoelectronic integration and will pave way to monolithically integrated graphene optoelectronic devices with silicon ICs for three-dimensional optoelectronic integrated circuit chips.

“…Nonlinear optical materials have numerous applications, including photodynamic therapy, nonlinear photonics, 3D optical data storage, frequency upconverted lasing, and fluorescence imaging [1][2][3][4][5]. One of the most important problems of applied nonlinear optics is the search for media with possibly large values of nonlinear susceptibilities.…”

⋍10-7 СГСЭ существенно превышают значения, вычисленные на основе модели, описывающей нелинейную восприимчивость электро-нов, находящихся в непараболичной зоне проводимос-ти. Показано, что наблюдаемое расхождение устра-няется, если в расчете учесть диссипацию энергии электронов. Рост эффективности при четырехвол-новом взаимодействии в узкозонных полупроводниках ограничивается нелинейным поглощением взаимодей-ствующих волн Ключевые слова: нелинейная восприимчивость третьего порядка, четырехволновое взаимодействие, узкозонные полупроводники, порог пробоя UDC 621.373.826
