FoV and Efficiency Optimization for Resonant Beam SLIPT with Telescope Integration
Abstract
Meeting the large bandwidth demands of wireless communication for mobile Internet of Things (IoT) devices while enhancing their endurance is a significant challenge. Simultaneous lightwave information and power transfer (SLIPT) technology offers the potential to realize wireless charging and signal transfer, making it suitable for supporting autonomous vehicles and drones. The resonant beam system (RBS) leverages the self-aligning property of a spatially distributed laser resonator (SSLR), allowing energy transmission from the transmitter to the receiver without mechanical alignment. However, the existing resonant beam SLIPT system exhibits a limited field of view (FoV) and transmission efficiency, facing challenges in practical applications. In this paper, we propose a resonant beam SLIPT system enhanced by incorporating an internal telescope and optimizing the communication, energy transfer, and FoV performance by solving the Pareto front set of the system's achievable performance region. The results indicate that the optimized FoV is increased by 17\%, reaching 26.8, while its average end-to-end efficiency is improved by 145\%, achieving 5.4\%.
