Preparation Of Nano Waveguide And Nonlinear Optical Effect

This paper mainly focuses on the unique properties of the optical nano-waveguides,the novel fabrication method of the new type nano-waveguides,discovery of the physics phenomenon and the optical effects.These new researches will be applied to the novel micro-nano optical devicesFirstly,this paper studies the waveguide properties of the optical nano-waveguides.A comparison is made to illustrate the differences between the two excitation methods:the direct irritation of the exciting light and the waveguide irritation.Then,the unique optical properties of the propagating light within the optical single nanowires is studies,e.g.the large scale regulative ability of the evanescent field,the mode polarization,the dispersion properties of the extraordinary wave and the surface enhanced effect.Secondly,the fabrication method and the procedure of the nano-wire waveguide and the characteristic of the nano waveguide are thoroughly studied.A conclusion can be drawn that the nano waveguide having a uniform and smooth surface can be fabricated by using the VLS method which provides a theoretical foundation for testing the non-linear optical properties of the waveguides.In addition,this paper also focuses on the nonlinear optical properties of semiconductor nanowires,which includes the nanowires and nanoribbons of CdS and ZnSe,and MoO₃ nanoribbons.A brief introduction of the nano-waveguide applications is also contained.Finally,the research of its application.Owe to these excellent properties of nano waveguides,the new photonic devices based on nano-waveguide core has been researched widely and deeply in many fields.These devices,such as beam splitter,sensors,filters,interferometers,gratings,etc,will play a guiding role in the development of science in the future.
