摘要光纤到户是目前宽带接入的最佳选择,然而,有些关键器件,如激光管和探测器的生产成本仍居高不下,对用户来说若要安装光纤到户其所需费用太高。因此,接入网“最后一公里”的价格太贵已成为通信业发展的瓶颈。本文提出采用波长为850nm和650nm的光互联网系统的新方案,从光纤材料、光通信器件(半导体激光器、光探测器和波长转换器)方面着手研究如何降低光接入网成本。本文以收发器的研制为目标,从器件的封装到模块的设计和系统测试开展了一系列工作。具体内容如下:1.用本课题组制备的硅(Si)的光电探测器芯片封装成PIN-TIA(跨阻抗放大器),并测试了相关参数,暗电流基本在1nA以下,响应度高于0.35mA/m...Abstract Fiber to the home is the best choice of broadband access at the present time. But the cost of some key devices, such as laser diodes and optical detectors,is still very high. It is too costly for the users to realize fiber to the home. So the high cost of the “last mile” access network has become the bottleneck of the communication development. The optical interconnection pr...学位:工学硕士院系专业:信息科学与技术学院电子工程系_电路与系统学号:20033001
