Metallic nanostructures give rise to bright and dark plasmon modes, and through their interactions can support a variety of coherent phenomena more typically associated with atomic systems, providing new sensing and energy transfer strategies.
It is significant research approach in the field of manipulation and sorting of a small size of particle and molecule with dimensions of tens to hundreds of nanometers in a microfluidic chip. It is a breakthrough research that provides new solutions and opportunities for a wide range of traditional micro-/nano-particle and molecule sorting, manipulation and detection by using optofluidic force. Also,...
Strong quasi-cw terahertz fields accelerate and recollide electron-hole pairs injected by a near-ir laser into GaAs quantum wells. A frequency comb is emitted, with up to 18 teeth separated by twice the terahertz frequency.
Focus will be where light and patient meet, and improvements yielding better outcomes, by detecting, characterizing and monitoring very small entities (molecules, cells) within the human body, quantitatively, dynamically, and preferably without contrast agents.
Loss in the metal is the main factor restricting practicality of plasmonic and metamaterial devices. In this tutorial the inevitability of the loss, its physical origins and the means to mitigate it will be considered
We review the recent progress on the first experimental demonstration of photonic topological insulators, along with a variety of new ideas associated with it.
Plasmonic assisted nanodetectors and LEDs may be the only solution for power efficient onchip optical communications - the holy grail of integrated photonics. Localized plasmons in novel detectors and fast LEDs will be described in detail.
Trapped ions are a key experimental platform for quantum computing, while photons transport information over long distances. Optical cavities provide a coherent link between these two systems, as demonstrated by recent experiments with calcium ions.
There is a pressing clinical need to provide image guidance during surgery. Currently, assessment of tissue that needs to be resected or avoided is performed subjectively leading to a large number of failures, patient morbidity and increased healthcare cost. Because near-infrared (NIR) optical imaging is safe, does not require contact, and can provide relatively deep information (several mm), it offers...
This tutorial reviews recent advances in the fundamental understanding and active control of quantum fluids of light in nonlinear optical media. Perspectives in the direction of strongly correlated photon systems are outlined.
Single organic molecules allow for the generation of high-flux single photons. At cryogenic conditions, these photons can be as narrow as a few MHz. It is possible to find suitable molecules matching to a variety of atomic transitions, allowing for quantum hybrid systems of atoms and molecules.
Development of ecologically-efficient UV water treatment has resulted in lower energy consumption and compact design, as well as a reduced carbon footprint compared to alternate technologies for environmental contaminant treatment such as activated carbon.
Organic materials combined with silicon waveguides offer a path to highly efficient electro-optical devices. Modulators based on this technology have already shown frequency responses up to 100 GHz, switching with as little as 0.6 fJ/bit, and operation up to 160 Gbit/s.
The application of a specific metal organice vapour phase epitaxy (MOVPE) growth process for (GaIn)As-based VECSEL using thermally more efficiently decomposing MO-group-V-sources results in an extended wavelength range and facilitates the necessary strain compensation of the highly compressive-strained (GaIn)As-quantum well layers by tensile-strained Ga(PAs) barrier layers. Applying a closed-loop-design...
193nm lithography has enabled semiconductor manufacturing to achieve nm resolution. Highest quality optical materials and optics are an essential part of this. Important optical properties of and test methods for these materials will be reported.
A novel finishing process, called Convergent Polishing, is described where the workpiece regardless of its initial shape will converge to final surface figure under a fixed, unchanging set of polishing parameters in a single iteration.
This presentation will provide an overview of surgical molecular navigation using fluorescence imaging to visualize key normal structures and diseased tissue in real time.
We present local investigations of the spectral evolution of ultrashort slow pulses as they propagate. We also show that nanoscale electrical and magnetic fields can be detected simultaneously.
Cheap and practical infra red (IR) sources are incandescent sources such as globar or hot membranes. These sources are broadband, omnidirectional, have a low efficiency and cannot be modulated faster than 100 Hz. In this paper, we show how it is possible to overcome all these limitations by taking advantage of surface waves.
