Toroidal Dipole-Dominated High-Performance Optical Sensors via Nanoimprinted Tetramer Architectures. [PDF]

Nanophotonics
We developed a scalable low‐cost nanoimprinted tetramer architecture (NTA) sensor using two‐step nanoimprint lithography. It comprises polystyrene nanopillar tetramer arrays on a PS waveguide and gold mirror, supporting a toroidal‐dipole‐mediated resonant mode at 810 nm with a simulated Q of 3124.

Review of nanophotonics approaches using nanostructures and nanofabrication for III-nitrides ultraviolet-photonic devices

, 2018
Group III-nitride semiconductor materials especially AlGaN are key-emerging candidates for the advancement of ultraviolet (UV) photonic devices. Numerous nanophotonics approaches using nanostructures (e.g., nanowires, nanorods, and quantum dots/disks ...

Dielectric Permittivity Tensor of Muscovite for Next Generation All Van Der Waals Broadband Photonic Components

Advanced Optical Materials, EarlyView.
Low‐index and low‐loss vdW muscovite represents an emerging robust dielectric platform for the creation of next‐generation all‐vdW nanophotonic architectures. Its utilization as a low‐index building‐block in all‐vdW multilayers enables extreme optical contrast when paired with MoS2, paving the way to the realization of few‐layer ultrathin DBS ...

Single‐Step Fabrication of Smart 3D Microstructures Exploiting Naphthopyrans as Photoinitiators and Photochromic Molecules

Advanced Optical Materials, EarlyView.
Naphthopyran–benzophenone compounds can act simultaneously as photoinitiators and photochromic molecules for two‐photon polymerization. Using a single‐step process, liquid photoresist is encapsulated within polymerized 3D microstructures, preserving reversible UV–vis photochromism after fabrication.

Known-Plaintext Attack and Ciphertext-Only Attack for Encrypted Single-Pixel Imaging

IEEE Access, 2019
In many previous works, a single-pixel imaging (SPI) system has been constructed as an optical image encryption system. Unauthorized users are not able to reconstruct the plaintext image from the ciphertext intensity sequence without knowing the ...

A nanophotonic laser on a graph [PDF]

Nature Communications, 2019
AbstractConventional nanophotonic schemes minimise multiple scattering to realise a miniaturised version of beam-splitters, interferometers and optical cavities for light propagation and lasing. Here instead, we introduce a nanophotonic network built from multiple paths and interference, to control and enhance light-matter interaction via light ...
