摘 要:为了提高光电技术实验教学效果,使学生更好地掌握光电技术实验技能,提出一种光电技术实验系统。该系统以实验室科研平台为基础,主要由信号源实验、光源实验、信号放大实验和系统接收测试实验4部分组成。在实验中,学生按照分组形式依次对4部分进行实验,分别测量从而各部分实验系统的性能,并分析其对应的理论知识。该实验教学系统的运行使学生对光电技术有了更深刻的理解,提高了教学质量,同时使学生通过体验真实的科研过程,为其将来的科研工作打下了基础。

Abstract: In order to enhance the effect of experimental teaching and enable students to better grasp experimental skills in optoelectronics technology, an optoelectronics experimental system for students is proposed and experimental demonstrated. This system is built on the basis of laboratory research platform. The experimental part includes a signal source, the experimental part of the light source, signal amplification system and experiment receive test parts. In the experiment, the students in the form of a packet must follow these four parts of experiments, and the performance of each part of the experimental system is measured, and theoretical knowledge is analyzed corresponding to the experimental results. After finished the experiments, it can make the students have a more profound understanding of the optoelectronics technology. The quality of the education of students in the laboratory can be improved. At the same time, it can make the students to experience the real research work, and establishes the foundation for students' future research work.

由于具有体积小、频带宽、损耗低和抗干扰能力强等优点,光纤通信系统已成为现代通信中最主要的信息传输手段[1-7]。在本科生与研究生教育中,光电技术是物联网工程、通信工程及电子信息工程专业一门重要的专业基础课,涉及的专业知识广泛、理论性较强。因此,光电技术及光纤通信课程必须设置实验教学内容,以便通过实验教学帮助学生理解光电子技术理论课程内容,提高学生实践动手能力与分析、解决问题的能力。目前,光电技术及光纤通信课程实验内容基本固定,且存在验证性实验过多等问题。为了提高光电技术及光纤通信原理实验的教学质量,切实提高学生的实践能力以及创新应用能力,需要改变传统实验教学方法,对光电子技术实验进行改革[8]。……
