Structure design and preparation of porous SiGe/Si heterostructure material microcavity

Abstract

提出了采用多孔SIgE/SI异质多层结构来获得布拉格反射镜方法.首先采用传输矩阵方法设计了多孔SIgE/SI异质材料微腔结构,并通过超高真空化学气相沉积与电化学阳极腐蚀相结合的方法实验制备了两种结构的微腔,同时对微腔进行光学性质表征,并详细讨论了实验结果.We propose a method for preparing the Bragg reflectors by porous SiGe/Si heterogeneous multilayer structure.Two kinds of structure of porous SiGe/Si microcavity are prepared through a method by combining ultra-high vacuum chemical vapor deposition and electrochemical anode,based on the numerical simulations of transfer matrix method.The optical properties of the microcavity are characterized,and the experimental results are discussed in detail.福建省省教育厅基金项目(JB11128);闽江学院科技启动项目(KQ1004
