A High Aspect Ratio Inverse-Designed Holey Metalens.
Nano letters (Print), 2021 Free-standing nanofins or pillar meta-atoms are the most common constituent building blocks in metalenses and metasurfaces in general. Here, we present an alternative metasurface geometry based on high aspect ratio via-holes.

High-aspect-ratio nanoimprint process chains [PDF]
Microsystems & Nanoengineering, 2017 AbstractDifferent methods capable of developing complex structures and building elements with high-aspect-ratio nanostructures combined with microstructures, which are of interest in nanophotonics, are presented. As originals for subsequent replication steps, two families of masters were developed: (i) 3.2 μm deep, 180 nm wide trenches were fabricated ...
