Metasurface spaceplates reach a millimeter-scale squeezed length of free space
Imon Kalyan, Raghvendra P. Chaudhary, Nir Shitrit
Metasurfaces offer compact flat lenses (metalenses) for miniaturized imaging systems; however, the utmost miniaturization requires not only metalenses but also a substantial reduct…
Orbit-orbit photonics: Harnessing vortex-trajectory interplay for light manipulation
Raghvendra P. Chaudhary, Imon Kalyan, Nir Shitrit
Light can carry a spin angular momentum, an intrinsic and extrinsic orbital angular momentum, associated with a circular polarization, optical vortex beams, and varying beam trajec…
Dammann Metasurface Route to Overcoming the Uniformity Defects in Two-Dimensional Beam Multipliers
Rinat Gutin, Raghvendra P. Chaudhary, Avraham Reiner +1
Dammann gratings - beam-shaping optical elements acting as beam multipliers with equal-power beams - are a key element in three-dimensional imaging based on structured light and be…
Localized Polymerization Using Single Photon Photoinitiators in Two-photon process for Fabricating Subwavelength Structures
Govind Ummethala, Arun Jaiswal, Raghvendra P Chaudhary +3
Localized polymerization in subwavelength volumes using two photon dyes has now become a well-established method for fabrication of subwavelength structures. Unfortunately, the two…
Sub-wavelength Lithography of Complex 2D and 3D Nanostructures without Dyes
Raghvendra P Chaudhary, Arun Jaiswal, Govind Ummethala +3
One-photon or two photon absorption by dye molecules in photopolymers enable direct 2D & 3D lithography of micro/nano structures with high spatial resolution and can be used effect…
One-step Patterning of Sub-wavelength Plasmonic Gratings in Metal-Polymer Composites
Raghvendra P Chaudhary, Govind Ummethala, Arun Jaiswal +3
2D and 3D micro/nano fabrication based on two-photon polymerization (TPP) has emerged as a strong contender for additive manufacturing for wide variety of applications. In this man…
Stanene: Atomically Thick Free-standing Layer of 2D Hexagonal Tin
Sumit Saxena, Raghvendra Pratap Choudhary, Shobha Shukla
Two dimensional (2D) layered materials have recently gained renewed interest due to their exotic electronic properties along with high specific surface area. The prospects of explo…
