Study On Optical Four-wave Mixing Based On Antimony And MXene

All-optical wavelength conversion(AWOC)is one of the key technologies to realize all-optical communication.At present,all-optical wavelength conversion technology is based on non-linear effect,which includes four categories: cross-phase modulation effect,cross-gain modulation effect,four-wave mixing effect and difference frequency generation.Among these three kinds of wavelength conversion technologies,all-optical wavelength converter based on four-wave mixing has attracted many scientists' attention for its' excellent characteristics.Compared with other all-optical wavelength converters,the new wavelength based on four-wave mixing can completely replicate the amplitude,frequency and phase information of the signal light,and achieve fully transparent wavelength conversion.Wavelength conversion based on four-wave mixing was proposed as early as ten years ago.However,due to the limitation of the medium's non-linear strength,the conversion efficiency has been low.It is urgent to find a medium with high stability and non-linear strength.In 2004,two physicists of the University of Manchester UK,Andre Geim and Konstantin Novoselov,first discovered graphene,which opened the door to the study of two-dimensional materials.Two-dimensional materials refer to planar materials in which electrons move freely only in two dimensions,such as nano-films,superlattices and quantum wells.The two-dimensional material is a kind of layered structure,the layer and layer by weak Vander Wa Alsley effect.Unlike one-dimensional and three-dimensional materials,two-dimensional materials have unique photoelectric properties because of their two-dimensional structure.At present,two-dimensional photoelectric materials mainly include graphene(GN),transition metal chalcogenides(TMDCs),topological insulators(TI),black phosphorus(BP),etc.Recently,two new two-dimensional materials — — Sb and MXene,have been discovered.These two two two-dimensional materials have high stability,highnon-linear strength and excellent thermal conductivity.They can be used as non-linear devices in all-optical signal processing.In this paper,all-optical wavelength conversion will be realized by combining antimony and MXene with micro-nano optical fibers.The main research contents are as follows:1.The principle of all-optical wavelength converter based on four-wave mixing is introduced,and the feasibility of Sb and MXene as wavelength conversion medium is explained in principle.2.The preparation and characterization of Sb and MXene were introduced,and the properties of the materials were introduced in detail.3.The wavelength conversion device based on SB and MXene and the experimental measurement are introduced.The construction of wavelength conversion device is introduced in detail.The conversion effect is measured by high-speed oscilloscope and spectrometer.The conversion performance and signal processing ability of the device are analyzed.
