Single-exposure holographic lithography of ultra-high aspect-ratio microstructures
Dajun Lin, Brian Baker, Rajesh Menon
Volumetric lithography offers a path to scalable fabrication of complex three-dimensional (3D) micro- and nanoscale architectures, yet existing approaches are limited by quasi-two-…

Generating non-diffracting bottle beams with a flat multi-level diffractive lens
Andra Naresh Kumar Reddy, Srinivasa Rao Allam, Ashish Tiwari +4
We introduce a novel method for creating a high-quality, sharply defined, non-diffracting optical bottle beam by focusing a Bessel beam propagating through a flat multi-level diffr…
