Wafer-scale photonic and plasmonic crystal sensors

George M.C., Liu J.-N., Farhang A., Williamson B., Black M., Wangensteen T., Fraser J., Petrova R., Cunningham B.T., Moxtek, US

This presentation will review recent results in 200 mm diameter wafer-scale fabrication, metrology, and optical modeling of various photonic and plasmonic crystal sensors, including 1D photonic crystals based on leaky-waveguide mode resonance, as well as [...]

Silicon Photonic Temeprature Sensors

Ahmed Z., NIST, US

For the past century, industrial temperature measurements have relied on resistance measurement of a thin metal wire or filament whose resistance varies with temperature. Though resistance thermometers can routinely measure industrial temperatures with uncertainties of [...]

Fabrication and Characterization of On-Chip Integrated Silicon Photonic Bragg Grating and Photonic Crystal Cavity Thermometers

Klimov N.N., Purdy T., Ahmed Z., National Institute of Standards and Technology / University of Maryland, US

Though today’s resistance thermometers can routinely measure temperatures with uncertainties of 10 mK, they are sensitive to environmental variables such mechanical shock and humidity, which cause the sensor resistance to drift over time requiring expensive, [...]

Energy Efficient Transmission Scheme Alternative to M-PAM for Short Range Data Communication

Elsherif M.A., Malekmohammadi A., The University of Nottingham, MY

Mapping Multiplexing Technique was reported for the ﬁrst time in [(patent No: PI201270063)] as an alternative modulation and multiplexing technique for high-speed optical fiber communication systems. In this letter two, three, and four-channel Mapping Multiplexing [...]

Highly Tunable Surface Plasmons Resonance Using Metal/metal Oxide Hybrid Nanostructures

Khosroabadi A.A., Gangopadhyay P., Norwood R.A., University of Arizona, US

Metal and metal oxide electrodes play a significant role in many cutting edge applications including photonics, membranes, biological supports, sensing, electrochromics, and in various green technologies, such as, photocatalytics, Li-ion batteries and photovoltaics. There is [...]

Plasmonic Structural Colors For Plastic Consumer Products

Højlund-Nielsen E., Clausen J., Thamdrup L.H., Zalkovskij M., Højlund-Nielsen E., Nielsen T., Mäkelä T., Ahopelto J., Mortensen N.A., Kristensen A., Technical University of Denmark, DK

Today colorants, such as pigments or dyes, are used to color plastic-based consumer products, either as base for solid colored bulk polymer or in inks for surface decoration. After usage, the products must be mechanically [...]

Effective Multistep Exciton Delivery Through DNA-based Photonic Wires

Spillmann C.M., Buckhout-White S., Ancona M.G., Cunningham P.D., Melinger J.S., Goldman E.R., Medintz I.L., Naval Research Laboratory, US

Energy manipulation at the nanoscale is a key requirement to develop next-generation nanotechnologies ranging from biosensing to light harvesting, yet the design rules of these nanoscale systems must first be optimized to accomplish their intended [...]

230 fold fluorescence enhancement by 3D Rhodamine B coated polystyrene photonic crystals

Eftekhari E., Li Q., Li X., Cole I.S., Li Q., Li X., Griffith University, AU

We report a 230-fold fluorescence enhancement with fluorescent polystyrene based three-dimensional (3D) colloidal photonic crystals (F-CPhCs) that can be readily fabricated over large areas. A simple and reproducible method was developed to synthesise novel fluorescent [...]

3D laser writing in-line process for the rapid fabrication of flexible electronic devices

Dubourg G., Marjanović S., Zlebic C., Matovic J., Crnojević Bengin V., Biosense Center, RS

In this work, we present for the first time a new approach of a 3D direct laser writing which allows the patterning of several layers in a single step by adjusting the parameters of the [...]

Transparent, Scalable, and Flexible Piezoelectric Pressure Sensors

Vishniakou S., UC San Diego, US

We present a pressure-sensitive ZnO thin-film transistor (TFT) as a potential technology for next-generation touchscreen. We discuss the properties of our devices and propose a structure that could be used to create transparent, scalable, and [...]
