Numerical Study of an Efficient Solar Absorber Consisting of Metal Nanoparticles

Nanoscale Research Letters, 2017
We propose and theoretically investigate an efficient solar light absorber based on a multilayer structure consisting of tungsten nanoparticle layers and SiO2 layers. According to our calculation, average absorbance over 94% is achieved in the wavelength

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 ...

Helicity‐Dependent All‐Optical Switching in Bi,Ga‐Substituted Rare‐Earth Iron Garnet Films Driven by Orbital Magnetic Moment

Advanced Optical Materials, EarlyView.
Helicity‐dependent all‐optical magnetization switching was demonstrated for the Bi‐ and Ga‐substituted rare‐earth (R) iron garnet crystal thin films (Bi,Ga:RIG; R = Eu3+, Nd3+, and Y3+). The efficiency followed the order EIG > NIG > YIG. These results show the correlation between 4f orbital moment (4f〈L〉) of R3+ and helicity‐dependent optical ...

An Australia/New Zealand optical communications ground station network for next generation satellite communications

, 2022
The limited bandwidth and security provided by radio frequency communications between the ground and space can be overcome with optical communications. The smaller beam divergence and high carrier frequency increase the bandwidth and brings with it the ...

Static Routing and Spectrum Assignment for Deadline-Driven Bulk-Data Transfer in Elastic Optical Networks

IEEE Access, 2017
Inter-datacenter services such as data replication and virtual machine migration contribute significantly to the underlying network traffic. These bulk-data transfer services can tolerate certain delay if the completion time is guaranteed with a pre ...

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.

Pointlike Material Accumulation and Displacement in Azopolymer Thin Films Driven by Spatial Light Modulation

Advanced Optical Materials, EarlyView.
A maskless, SLM‐driven approach enables the deterministic inscription of arbitrary topographical features in azopolymer films by mapping complex vectorial light fields onto local viscoplastic stress. This platform allows for the rapid generation and dynamic erasure of high‐aspect‐ratio micro‐spikes, offering a versatile tool for reconfigurable flat ...

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation

Advanced Optical Materials, EarlyView.
A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.
