Contribution
It introduces a novel fabrication method for 3D invisibility cloaks at visible wavelengths using stimulated-emission-depletion inspired direct-laser-writing lithography.
Findings
Successful creation of polarization-independent invisibility cloak
Operation demonstrated at visible light wavelengths
High-resolution 3D structuring achieved with diffraction-unlimited resolution
Abstract
We fabricate and characterize a three-dimensional polarization-independent invisibility cloak operating at visible wavelengths of light. The required drastic miniaturization has become possible by employing stimulated-emission-depletion inspired direct-laser-writing optical lithography with conceptually diffraction-unlimited axial and lateral resolution.
