In this Letter, high-speed optical wireless communication (OWC) with three light-emitting diodes (LED) and five micro-LEDs (μLEDs) is proposed as a proof-of-concept wavelength division multiplexing (WDM) system. It covers a wide spectrum from deep ultraviolet (UV) to visible light and thus could offer both visible light communication (VLC) and UV communication simultaneously. An aggregated data rate of up to 25.20 Gbps over 25 cm free space is achieved, which, to the best of our knowledge, is the highest data rate for LED-based OWC ever reported. Among them, the five μLEDs offer a data rate of up to 18.43 Gbps, which, to the best of our knowledge, is the highest data rate for μLED-based OWC so far. It shows the superiority and potential of μLEDs for WDM-OWC. Additionally, a data rate of 20.11 Gbps for VLC is achieved.
在本信函中，提出了一种采用三个发光二极管（LED）和五个微型发光二极管（μLED）的高速光无线通信（OWC），作为一种概念验证的波分复用（WDM）系统。它覆盖了从深紫外（UV）到可见光的广泛光谱，因此可以同时提供可见光通信（VLC）和紫外通信。在25厘米的自由空间上实现了高达25.20 Gbps的聚合数据速率，据我们所知，这是有史以来基于LED的OWC所报道的最高数据速率。其中，五个μLED提供了高达18.43 Gbps的数据速率，据我们所知，这是迄今为止基于μLED的OWC的最高数据速率。它展示了μLED在波分复用光无线通信中的优越性和潜力。此外，还实现了20.11 Gbps的可见光通信数据速率。
