摘要
利用自聚焦透镜代替集成的波分复用器件,对2路波分复用实验结构进行了改进,并在实验中增加光谱仪用于观察光纤中的光谱.通过上述改进,使学生进一步了解波分复用器内部结构,加深对复用和解复用的理解.
Utilizing two self-focusing lens to replace the integrated wavelength-division multiplexing devices,the wavelength-division multiplexing experimental structures were improved.Additionally,a spectrometer was used to obtain the spectra of fiber.Based on the above improvements,the students can learn more about the internal structure of wavelength-division multiplexing device and have a deeper understanding of wavelength-division multiplexing.
