Fullwave Maxwell inverse design of axisymmetric, tunable, and multi-scale multi-wavelength metalenses by Christiansen, Rasmus E.; Lin, Zin; Carmes, Charles Roques; Salamin, Yannick; Kooi, Steven E.; Joannopoulos, John D.; Soljačić, Marin; Johnson, Steven G. is a scholarly article available to read on EtoBox.
What is Fullwave Maxwell inverse design of axisymmetric, tunable, and multi-scale multi-wavelength metalenses about?
We demonstrate new axisymmetric inverse-design techniques that can solve problems radically different from traditional lenses, including \emph{reconfigurable} lenses (that shift a multi-frequency focal spot in response to refractive-index changes) and {\emph{widely separated}} multi-wavelength lenses ($\lambda = 1\,\mu$m and $10\,\mu$m). We also present experimental validation for an axisymmetric inverse-designed monochrome lens in the near-infrared fabricated via two-photon polymerization. Axisymmetry allows fullwave Maxwell solvers to be scaled up to structures hundreds or even thousands of wavelengths in diameter before requiring domain-decomposition approximations, while multilayer topology optimization with $\sim 10^5$ degrees of freedom can tackle challenging design problems even when restricted to axisymmetric structures.
