Abstract

As communication technology continues to develop, the demand for capacity and spectrum resources is also increasing. With the abundant spectrum resources and high energy efficiency, optical wireless communication (OWC) has become one of the key technologies in future wireless communication systems. However, due to the high frequency characteristics of optical signals, traditional OWC systems, such as free space optical communication (FSO) and visible light communication (VLC), suffer from low degrees of freedom, low robustness, and low energy efficiency, which limits its application. Optical reconfigurable intelligent surface (ORIS), as a new type of optical communication device, can change the direction, shape, amplitude, phase, and other characteristics of the optical beam. ORIS is expected to improve the defects and expand the application scenarios of OWC systems. In this article, we provide an overview of ORIS technologies and architectures, study typical cases of ORIS-aided OWC systems, and highlight key challenges in this area.

光学可重构智能表面辅助光学无线通信:机遇、挑战和趋势

随着通信技术的不断发展，对容量和频谱资源的需求也在不断增加。光无线通信以其丰富的频谱资源和高能效成为未来无线通信系统的关键技术之一。然而，由于光信号的高频特性，传统的光通信系统，如自由空间光通信(FSO)和可见光通信(VLC)，存在自由度低、鲁棒性低、能量效率低等问题，限制了其应用。光可重构智能表面(ORIS)作为一种新型的光通信器件，可以改变光束的方向、形状、幅度、相位等特性。ORIS有望改善OWC系统的缺陷，扩展OWC系统的应用场景。在本文中，我们概述了ORIS技术和体系结构，研究了ORIS辅助OWC系统的典型案例，并强调了该领域的关键挑战。
