摘要
Visible light communication(VLC)based on the micro light emitting diode(micro-LED)has attracted increasing attention owing to its high bandwidth,low power consumption,and high security.Compared with semi-polar or non-polar micro-LEDs,the commercial polar micro-LED has the advantages of low cost and more mature epitaxy technique.In this study,green micro-LEDs with different indium tin oxide(ITO)sizes are fabricated based on the commercial c-plane LED epitaxial wafer.The transmission performance of 80,100,and 150μm devices has been studied in detail.A partial pre-equalization scheme is utilized to increase data rates.Finally,the VLC system with a 100μm green micro-LED as the transmitter could achieve a maximum data rate of 3.59 Gbit/s.Such a result will be beneficial to promote the further development of low-cost,high-speed VLC devices in the future.
