Abstract
Our study presents recent progress in modelling and performing lens optical design with metasurfaces. We developed semi-analytical models that recover the output phase, polarization, dispersion and group delay of various nanostructures. This enables the mixing of different nanostructures to obtain a target dispersion profile an interesting application of the model. These models can readily be implemented within optical design software such as Zemax and use the built-in optimization of optical design processes while avoiding time-consuming electrodynamics computation. We also introduce the metasurfaces to the analytical lens design framework. This enables us to analytically compute the phase profile of freeform metasurface doublet concerning particular ray conditions such as the Abbe Sine condition as we presented here.
