Journal ArticleDOI
Lithographically-generated 3D lamella layers and their structural color
TL;DR: This work offers direct proof of the structural blue/green color via lithographically-replicated PMMA/air multilayers, analogous to those in real Morpho butterfly wings, and breaks through the bottleneck in technical development toward broad applications in gas/liquid sensors, 3D meta-materials, coloring media, and infrared imaging devices, etc.
Journal ArticleDOI
Processing study of SU-8 pillar profiles with high aspect ratio by electron-beam lithography
TL;DR: In this paper, the fabrication of micro-pitched SU-8 pillar arrays with height up to 5µm and aspect ratio of 7.14:1 by electron beam lithography (EBL) at 100keV, combined with a hot developing process was reported.
Journal ArticleDOI
Precision integration of grating-based polarizers onto focal plane arrays of near-infrared photovoltaic detectors for enhanced contrast polarimetric imaging
TL;DR: In this paper, the integration of large-scale polarizers onto the chips of FPAs with individual indium gallium arsenide/indium phosphide (InGaAs/InP) sensors as the basic building blocks has been successfully manufactured.
Journal ArticleDOI
Research on polarization performance of InGaAs focal plane array integrated with superpixel-structured subwavelength grating
TL;DR: The imaging results show that the fabricated polarimetric InGaAs FPA presents a more obvious profile for artificial objects, compared to the conventional detector, which indicates a good capability of near-infrared polarization detection.
Journal ArticleDOI
Reconstructing a plasmonic metasurface for a broadband high-efficiency optical vortex in the visible frequency
TL;DR: The fabricated metasurface based on the parameters by theoretical optimization demonstrates a high quality vortex in optical frequencies with a significantly enhanced efficiency of over 20% in a broad waveband.
