Theoretical And Experimental Research On Single-mode Optical Fiber Based On CuInS₂ Quantum Dot Coating

CuInS₂ as a semiconductor quantum dot,has been applied in the fields of solar cells,LEDs,bioluminescent probes.At this stage,CuInS₂ has little research on the optical properties of optical fibers and the 1.2-2.4mm.The theoretical and experimental aspects of single-mode fiber based on CuInS₂ quantum dot coating are studied.The main innovations and research contents are the following aspects:?1?The CuInS₂ was prepared by solvothermal method.The precursor material ratio of 0.070gCul and 0.464gIn?C₂H₃0₂?₃ was used.The molar ratio of Cu/In was about 1:4.Measure its UV absorption spectrum,PL emission,XRD,Raman spectrum.Use Martial studio to model the structure of CuInS₂,optimize the structure,modify the band gap with scissors operator,and simulate the dielectric constant,refractive index,reflection coefficient and other properties of the material.?2?In the experimental aspect,CuInS₂ quantum dot was coated with bare fiber Instead of the coating of single-mode fiber,study the transmission characteristics of CuInS₂ combined with single-mode fiber under 1.2-2.4mm.The effects of solution mass fractionw,coating length L and other factors on the supercontinuum transmission of CuInS₂ combined with single-mode fiber were studied.Rsoft software was used to establish a CuInS₂ layer coated optical waveguide model.Observe the output optical power change of the model at 1.6-2.4mm and compare it with the experimental results.?3?An optical attenuator was prepared,packaged with quartz capillary,UV curing adhesive,to determine the structural parameters of the device.The transmission characteristics of the prepared optical attenuator were studied and analyzed,and its temperature stability at 0-50?was measured.It is proposed to use CuInS₂ optical attenuator to equalize the power of multi-wavelength laser output and perform numerical simulation.
