Fabrication of Field-Sequential Color Display Using Predesigned Ferroelectric Liquid Crystals
A novel series of low transition temperature and fast response chiral Smectic C (SmC*) liquid crystals was designed and synthesized. Phase transition behaviors and electro-optical properties of the synthesized compounds were investigated and compared. Ferroelectric [...]
Effects of Heat Treatment of ZnS Nanoparticles Prepared by Hydrothermal Synthesis on Microstructure and Optical Properties in Spark Plasma Sintering (SPS)
Hong Y.W., Yeo S.Y., Paik J.H., Cho J-H., Jeong Y.H., Yun J.S., Park W.I., Korea Institute of Ceramic Engineering & Technology, KR
Zinc sulfide (ZnS) is one of the most widely used infrared transmitting window and lens materials for systems operating in the long wave range (8~12 ㎛). ZnS nanoparticles have been intensively studied because of their [...]
Resuable Moth-Eye nano-patterned PDMS sticker with a versatile function of coating for photovoltaics.
In solar photovoltaic systems, enhancing absorption of the incident light on the device surface through reducing reflection is crucial for improving the system performance. In the traditional layered method for anti-reflective coatings (ARCs), however, there [...]
Giant Enhancement of the Chiro-Optic Response of Chiral Plasmonic Media using Structured Light
Reddy I.V.A.K., Sukhotskiy V., Baev A., Furlani E.P., Prasad P.N., Haus J.W., University at Buffalo (SUNY), US
We propose an approach to achieve a great enhancement and broad spectral tunability of the chiro-optic response of plasmonic metasurfaces by exploiting their interaction with light of complex polarization, endowed with both spin (SAM) and [...]
Numerical Modelling of a Sinusoidal Grating-Based Surface Plasmon Coupled Emission Biosensor
We present a full-wave computational model to study the optical behavior of a versatile sinusoidal grating-based surface plasmon-coupled emission (SPCE) biosensor. Surface plasmons (SPs) are coherent oscillations of conduction electrons on a metal surface excited [...]
Design of 160-Channel Si3N4 based AWG-Spectrometer for Medical Applications
Seyringer D., Burtscher C., Edlinger J., Maese-Novo A., Muellner P., Hainberger R., Kraft J., Koppitsch G., Meinhardt G., Sagmeister M., Vorarlberg University of Applied Sciences, AT
We present the design of 160-channel, 50-GHz Si3N4 based AWG applying our proprietary AWG-Parameters tool. For the simulations of the AWG layout, we used PHASAR photonics tool from Optiwave. The simulated transmission characteristics were then [...]
Visible-Blind Ultraviolet Photodetectors Based on NiO/ZnO NRs with Poly-(N-vinylcarbazole) Intermediate Layer
Ultraviolet (UV) photodetectors (PDs) have useful applications including flame detection, environmental monitoring, early missile threat warning systems, etc. UV PDs based on wide-band-gap materials, such as GaN and ZnO have a visible-blind advantage over silicon-based [...]
Electrochemical Nanoimprinting of Silicon: A Direct Patterning Approach
Soft-lithography and nanoimprinting lithography have been critical in manufacturing 3D features with sub-20 nm resolution onto polymeric materials which have often been employed for producing micro and nanoscale optical materials and surfaces. However, methods for [...]
Real-Time Density Functional Tight Binding: A New Computational Tool for Probing Electronic Properties of Plasmonic Systems
Light-harvesting systems and plasmonic materials continue to garner significant attention due to their importance in both energy conversion and sensitive detection technologies. However, several challenges exist in improving their performance: these electronic multifunctional systems are [...]
