Experimental realization of the active convolved illumination imaging technique for enhanced signal-to-noise ratio
Wyatt Adams, Anindya Ghoshroy, Durdu O. Guney
Imaging is indispensable for nearly every field of science, engineering, technology, and medicine. However, measurement noise and stochastic distortions pose fundamental limits to…
Plasmonic Superlens Imaging Enhanced by Incoherent Active Convolved Illumination
Wyatt Adams, Anindya Ghoshroy, Durdu Ö. Güney
We introduce a loss compensation method to increase the resolution of near-field imaging with a plasmonic superlens that relies on the convolution of a high spatial frequency passb…
Active plasmon injection scheme for subdiffraction imaging with imperfect negative index flat lens
Anindya Ghoshroy, Wyatt Adams, Xu Zhang +1
We present an active physical implementation of the recently introduced plasmon injection loss compensation scheme for Pendry's non-ideal negative index flat lens in the presence o…
Hyperbolic Metamaterial Feasible for Fabrication with Direct Laser Writing Processes
Xu Zhang, Sanjoy Debnath, Durdu Ö. Güney
Stimulated emission depletion microscopy inspired direct laser writing (STED-DLW) processes can offer diffraction-unlimited fabrication of 3D-structures, not possible with traditio…
Multi-resonant silver nano-disk patterned thin film hydrogenated amorphous silicon solar cells for Staebler-Wronski effect compensation
Ankit Vora, Jephias Gwamuri, Joshua M. Pearce +2
We study polarization independent improved light trapping in commercial thin film hydrogenated amorphous silicon (a-Si:H) solar photovoltaic cells using a three-dimensional silver…
On Negative Index Metamaterial Spacers and Their Unusual Optical Properties
Muhammad I. Aslam, Durdu Ö. Güney
We theoretically investigate the possibility of using a metamaterial structure as a spacer, named as metaspacer, which can be integrated with other materials in microfabrication. W…
