The Fano Signature in the Optical Response of a Waveguide-excited Compound Plasmonic Nanoantenna
Hardik Vyas, Ravi Hegde
While long-range propagating plasmons have been extensively investigated for implementing on-chip optical sensing platforms, waveguide-excited localized surface plasmon resonance (…
High-transmissivity Silicon Visible-wavelength Metasurface Designs based on Truncated-cone Nanoantennae
Krupali D. Donda, Ravi S. Hegde
High-transmissivity all-dielectric metasurfaces have recently attracted attention towards the realization of ultra-compact optical devices and systems. Silicon based metasurfaces,…
Polarization tunable all-dielectric color filter based on cross-shaped Si nanoantennas
Vishal Vashistha, Gayatri Vaidya, Pawel Gruszecki +2
Color filters have important applications in the area of Nano-spectroscopy and ccd imaging applications. Metallic nanostructures provide an efficient way to design and engineer ult…
All-Dielectric Metasurfaces Based on Cross-Shaped Resonators for Color Pixels with Extended Gamut
Vishal Vashistha, Gayatri Vaidya, Ravi S Hegde +3
Printing technology based on plasmonic structures has many advantages over pigment based color printing such as high resolution, ultra-compact size and low power consumption. Howev…
The Zero-n Gap Soliton
Ravi S. Hegde, Herbert G. Winful
Periodic structures consisting of alternating layers of positive index and negative index materials possess a novel band gap at the frequency at which the average refractive index…
Transmission properties of periodic nonlinear structures containing left handed materials
Ravi S. Hegde, Herbert G. Winful
We study the transmission properties of a nonlinear periodic structure containing alternating slabs of a nonlinear right handed material and a linear left handed material. We find…
