微波光纤传输专业实验设计与实践

Design and practice of radio over fiber experiment for regular college course

基于将科研资源融入本科教学工作,并进而转化为优质教学资源的基本理念和目标定位,开展了将微波光纤传输科研实验转化为本科生可操作的专业实验的探索与实践,设计了电光调制器半波电压测量、微波光纤传输损耗分析、偏离线性工作点下传输信号特性表征三部分实验教学内容并进行了教学实践。该实验帮助学生了解微波光子学前沿,理解微波光纤传输的基本原理和主要性能参数,掌握半导体激光器、电光调制器、光电探测器、光功率计、频谱分析仪等器件设备的工作原理和操作技能,培养学生专业知识运用、科学问题研究、创新实践探索等方面的综合能力。

Based on the idea and target orientation of integrating scientific research resources into the undergraduate teaching,and then into high quality teaching resources,the conversion of the radio over fiber（ Ro F） experiment in scientific research to the operational specialty experiment for regular college course is explored and practiced. Three teaching subjects,the half-wave voltage measurement of electro-optic modulator,the loss analysis of Ro F system,and the signal characterization at the condition of departure from linear point,are designed and practiced. Through the experimental course,the students could understand the fundamental theory and main characteristic parameters of Ro F,and master the working principle and operation skill of semiconductor laser,electro-optic modulator,photo detector,optical power meter,and spectrum analyzer,etc. The comprehensive capabilities,including specialty knowledge usage,scientific problem investigation,innovative practice and exploration can be cultivated.The specialty experiment course provides helpful attempt for the effective integration of science research and teaching.
