Journal ArticleDOI
Generation of high-order Laguerre–Gaussian modes by means of spiral phase plates
TL;DR: The high quality of the output beams confirms the applicability of these phase plates for the generation of high-order LG beams and compares with theoretical models and numerical simulations.
Journal ArticleDOI
Fabrication and characterization of high-quality spiral phase plates for optical applications
TL;DR: In this paper, a three-dimensional fabrication process by electron beam lithography was finely tuned in order to realize high-quality spiral phase plates (SPPs) for the generation of OAM-carrying optical beams.
Journal ArticleDOI
Nanoporous gold plasmonic structures for sensing applications
TL;DR: Due to its superior response, nanoporous gold patterns appear promising for the realization of compact plasmonic platforms for sensing purposes.
Journal ArticleDOI
