On-chip light control of semiconductor optoelectronic devices using integrated metasurfaces

Semiconductor optoelectronics devices, capable of converting electrical power into light or conversely light into electrical power in a compact and highly efficient manner represent one of the most advanced technologies ever developed, which has profoundly reshaped the modern life with a wide range of applications. In recent decades, semiconductor technology has rapidly evolved from first-generation narrow bandgap materials (Si, Ge) to the latest fourth-generation ultra-wide bandgap semiconductor (GaO, diamond, AlN) with enhanced performance to meet growing demands. Additionally, merging semiconductor devices with other techniques, such as computer assisted design, state-of-the-art micro/nano fabrications,…
