Abstract

Micro-LED arrays exhibit high brightness, a long lifespan, low power consumption, and a fast response speed. In this paper, we have proposed a series-biased micro-LED array by using a nitride layer with multi-quantum wells epitaxial on sapphire substrate. The III-nitride multiple quantum wells serving as the micro-LED active material enable both luminescence and detection functionalities. The micro-LED array combines lighting, detection, and communication capabilities. We have conducted a thorough analysis of the micro-LED array's optoelectronic features in both lighting and detection modes. We also explore visible light communication performance across different arrangements of single micro-LED devices within the series-biased array. Our research achieves 720p video transmission via visible light communication using the micro-LED array, supporting a communication rate of up to 10 Mbps. Our contributions encompass the successful integration of lighting and detection functions and a comprehensive assessment of optoelectronic and communication performance. This study highlights the multifunctional micro-LED array's potential as a transceiver terminal in visible light communication systems, expanding its applications from smart lighting to visible light communication and photonic integrated chips. These innovations enhance our understanding of micro-LED technology and its versatile applications.

摘要

微发光二极管阵列具有高亮度、长寿命、低功耗和快速响应速度。在本文中，我们提出了一种串联偏置的微发光二极管阵列，它通过在蓝宝石衬底上外延生长具有多量子阱的氮化物层来实现。用作微发光二极管有源材料的III族氮化物多量子阱同时具备发光和探测功能。该微发光二极管阵列结合了照明、探测和通信能力。我们对微发光二极管阵列在照明和探测模式下的光电特性进行了全面分析。我们还研究了串联偏置阵列中单个微发光二极管器件的不同排列方式下的可见光通信性能。我们的研究通过使用微发光二极管阵列实现了720p视频的可见光通信传输，支持高达10Mbps的通信速率。我们的贡献包括成功集成照明和探测功能，以及对光电和通信性能的全面评估。这项研究突出了多功能微发光二极管阵列作为可见光通信系统中收发终端的潜力，将其应用从智能照明扩展到可见光通信和光子集成芯片。这些创新增进了我们对微发光二极管技术及其广泛应用的理解。
