摘要
基于白光发光二极管(LED)的可见光通信、照明两用系统近年来得到广泛的研究,然而普通LED性能制约了可见光通信调制带宽。为进一步提高LED的调制带宽,可采用微尺寸LED。简要阐述了提高LED调制带宽的方法,综述了近年来在优化可见光通信调制带宽的微尺寸LED性能方面的进展,指出了未来微尺寸LED的研究方向。
The visible light communication lighting system based on white light emitting diode(LED)has been widely studied.However,the performance of ordinary LED restricts the modulation bandwidth of visible light communication.In order to further improve the modulation bandwidth of LED,micro-size LED can be used.This paper briefly describes the methods to improve the modulation bandwidth of LED,and summarizes the progress in optimizing the performance of micro-size LED in visible light communication in recent years,and points out the research direction of micro-size LED in the future.
