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
