摘要

Abstract

The sophisticated shaping of electromagnetic field landscapes

both outside and inside optical cavities

has long been an important goal of optics and photonics

with broad applications in near-field imaging

lithography

and laser science. Despite extensive progress in far-field shaping of extracavity landscapes

achieving accurate tailoring of three-dimensional intracavity fields has remained elusive. Here

we propose full-space adjoint-enabled freeform meta-optics for complex

on-demand vector field shaping of intracavity landscapes. In contrast with conventional semi-space adjoint approaches

the full-space adjoint strategy allows for efficient full-wave optimization of vector fields at the subwavelength scale

overcoming strong multiple scattering and interference intrinsic to enclosed cavity boundaries. We experimentally demonstrate tailored plasmonic cavity landscapes with a freeform metasurface mask

realizing a fivefold enhancement in imaging fidelity without sacrificing optical super-resolution performance. Our work significantly broadens the scope of freeform meta-optics and may open new avenues for applications in nanophotonics

topological photonics

and quantum optics.
