摘要

面向室内高速接入、短距互连与显示和通信一体化等新兴场景，可见光通信（VLC）正由照明附加通信转向以光源阵列为核心的并行信息承载平台。微发光二极管（Micro-LED）凭借可规模化阵列集成、空间复用及片上互连潜力等技术，使发射端从单点光源演进为可编程并行前端，成为推动可见光高速通信工程化的重要器件。文章按“机理-器件-系统”的主线综述了高速Micro-LED器件及其VLC系统的最新进展：阐明了电光带宽的形成机制及主导因素随尺寸与注入条件的转移；总结了晶向与极化调控、量子阱与势垒及电子阻挡层设计、掺杂与应力能带工程、侧壁损伤抑制与钝化等提速路径及其对“带宽-效率/光功率”折中的影响；归纳了高谱效调制、均衡与预失真、阵列并行与多维复用等系统技术，并讨论了器件与系统层面的瓶颈与趋势，为后续协同优化与工程化部署提供了参考。

Abstract

For emerging scenarios such as high-speed indoor access

short-reach interconnects

and display-communication convergence

Visible Light Communication (VLC) is shifting from “illumination with added communication” toward a parallel information-bearing platform centered on emitter arrays. Leveraging scalable array integration

spatial reuse

and the potential for on-chip interconnects

Micro-Light-Emitting Diodes (Micro-LED) enable the transmitter to evolve from a single-point source into a programmable parallel emitting front end and have become a key enabler for the engineering deployment of high-speed VLC. Following a “mechanism-device-system” storyline

this review summarizes recent advances in high-speed Micro-LED devices and Micro-LED-based VLC systems. We elucidate the physical origins of electro-optical bandwidth and the regime-dependent transition of dominant limiting factors with device size and injection conditions. We then investigate the acceleration strategies including crystal-orientation and polarization engineering

quantum-well/barrier and electron-blocking-layer designs

doping and strain-induced band engineering

and sidewall-damage suppression and passivation

highlighting their trade-offs between bandwidth-efficiency and optical power. Furthermore

we outline system-level techniques such as spectrally efficient modulation

equalization and predistortion

array-based parallel transmission

and multi-dimensional multiplexing. We also discuss remaining bottlenecks and trends at both device and system levels

providing guidance for future co-optimization and practical deployment.
