EurekAlert  March 8, 2021 Critical challenges for real-world applications of flat optics technology are due to the limited operational efficiency in the visible region, on average lower than 60%, which originates from absorption losses in wavelength-thick structures and the realization of on-demand optical components for controlling vectorial light at visible frequencies simultaneously in both reflection and transmission and with a predetermined wavefront shape. Researcher in Saudi Arabia have developed an inverse design approach that allows the realization of highly efficient (up to 99%) ultrathin (down to 50 nm thick) optics for vectorial light control with broadband input–output responses in the visible […]
