Steerable dispersed beam for wireless optical power transfer

Abstract

This study provides a novel two-dimensional beam steering mechanism that takes advantage of wireless optical power systems utilizing diverging angular dispersion laser beams and the resonant beam charging technique. The system exhibits significant improvements compared to conventional systems that utilize pencil beams. These enhancements include reducing scanning time, capable of mitigating inherent errors, and increasing the ability to charge resonant cavities continuously. Specifically, our system exhibits scanning times that are 1.2 times faster than traditional systems. This opens the pathway for practical deployments of beam steering for RBC-based WOPT, enabling real-time charging and communication.
