Inverse design in flat optics
Published in Photonics and Nanostructures - Fundamentals and Applications, 2022
Due to the sub-wavelength resolution, compact size, and ease of integration, flat optics has emerged as a pivotal player for applications in iffractive metalens, structured-light generation, holograms, nonlocal metasurfaces, etc. In the design of flat optics devices, the traditional forward design method demonstrates insurmountable limitations while inverse design has developed into an indispensable approach to focus designers only on highlevel optical functionalities while handing over the task of finding conforming structures to machines. Here, we outline a cross-section of main advances of inverse design in flat optics: moving from basic theories and algorithms to further developments and diversified applications.
