摘要/Abstract

摘要：

以日盲紫外光通信系统多采用激光器或汞灯作为光源、紫外光电二极管作为探测器,整体系统体积大、操作复杂,难以满足电子通信工程的实验教学需求,因此急需建立一种新型光通信创新实验教学平台。文中设计并构建了一套新型紧凑化日盲紫外光通信系统,其采用紫外LED作为光源、可见光PIN管为探测器,以下转换荧光玻璃为光谱转换器,实现了远距离、高灵敏度的日盲紫外光信号传输与探测。该系统不仅增大了输出信号的幅值,还将最大日盲紫外探测光电流提高到了23.3 μA。通过实践教学,发现该创新实验平台对提高学生综合能力和对日盲紫外光通信实验仪器设备的理解与高效率使用,发挥了重要的促进作用。

Abstract:

E laser/mercury lamp and ultraviolet photodiode were mostly used as the light source and the detector in the solar blind ultraviolet communication system. The overall system was difficult to meet the experimental teaching requirements of electronic communication engineering for their large in volume and complicated in operation. Therefore, it was urgent to establish a new innovative experimental teaching platform of optical communication. In this paper, a new compact solar blind ultraviolet communication system was designed and constructed, which used ultraviolet LED as the light source, visible PIN tube as the detector, and the fluorescent glass as the spectrum converter to realize long-distance and high-sensitivity solar blind ultraviolet transmission and detection. This novel system not only increased the output signal amplitude, but also increased the maximum photocurrent to 23.3 μA. Through practical teaching, it was found that the innovative experimental platform played an important role in improving comprehensive ability, understanding and efficient of students to use of solar blind ultraviolet communication experimental equipment.

Key words: innovative experiment, solar blind ultraviolet, optical communication, teaching research, fluorescent glass, quantum cutting
