Demonstration of GaN optical power converter with 60% power conversion efficiency
Abstract
Abstract We demonstrate a GaN optical power converter (OPC) achieving a power conversion efficiency of 60.2% under monochromatic light illumination at 401 nm. The device maintains high performance under a high illumination intensity of 96 W cm −2 and at a high temperature of 125 °C. These results highlight GaN OPCs as a viable platform for a variety of applications, including optical wireless power transfer, power-over-fiber links, and electrically isolated power delivery.
