Profilometry and stress analysis of suspended nanostructured thin films
Ali Akbar Darki, Alexios Parthenopoulos, Jens Vinge Nygaard +1
The profile of suspended silicon nitride thin films patterned with one-dimensional subwavelength grating structures is investigated using Atomic Force Microscopy. We first show tha…

Optical spatial differentiation with suspended subwavelength gratings
Alexios Parthenopoulos, Ali Akbar Darki, Bjarke R. Jeppesen +1
We demonstrate first- and second-order spatial differentiation of an optical beam transverse profile using thin suspended subwavelength gratings. Highly reflective one-dimensional…
