Parameter Investigation for Stamp Manufacturing of Complex 3D Geometries Using Nanoimprint Lithography

open access: yesAdvanced Materials Technologies, EarlyView.
Nanoimprint lithography can replicate complex 3D microstructures with undercuts using single‐layer polymer stamps of different elasticities. By combining experiments and simulations, T‐shaped geometries and suitable undercut radii were identified that minimize stress and defects during demolding.

Basis‐Independent Geometric Phase Modulation in Circularly Birefringent Plasmonic Structures

open access: yesAdvanced Optical Materials, EarlyView.
Here we introduce a plasmonic metasurface composed of spatially rotated chiral spiral unit cells designed to produce space‐variant circular retardance. This generates a geometric phase ramp equivalent to a blazed grating, leading to polarization dependent diffraction orders in momentum space.
