Abstract

Simultaneous lightwave information and power transfer (SLIPT) technology offers a promising solution to address the communication and power demands of Internet of Things (IoT) devices. The resonant beam (RB) system, based on the self-aligning properties of a spatially separated laser resonator (SSLR), enables energy transmission without precise alignment. However, existing RB-based SLIPT systems are limited to single-receiver configurations. This work introduces a multi-receiver RB-SLIPT system capable of simultaneously transmitting energy and information to multiple receivers. An analytical model based on multi-mode rate equations and diffraction transmission theory is developed to evaluate the energy transfer and communication performance in multi-receiver scenarios. Numerical simulation results demonstrate that in a dual-receiver scenario, the proposed system is capable of transmitting 2 W of optical power to each receiver while achieving a communication capacity of 5.8 bit/s/Hz.

基于共振光束的移动SLIPT多接收机传输分析

同步光波信息和功率传输（SLIPT）技术为解决物联网（IoT）设备的通信和功率需求提供了一个有前途的解决方案。谐振光束（RB）系统基于空间分离激光谐振器（SSLR）的自对准特性，实现了无需精确对准的能量传输。然而，现有的基于rb的SLIPT系统仅限于单接收器配置。本工作介绍了一种能够同时向多个接收器传输能量和信息的多接收器RB-SLIPT系统。基于多模速率方程和衍射传输理论，建立了多接收机场景下能量传输和通信性能的分析模型。数值仿真结果表明，在双接收机场景下，该系统能够向每个接收机发送2w的光功率，同时实现5.8 bit/s/Hz的通信容量。
