Auto assembled Ag-ZnO  star shaped nanostructures depicted in figure 1, presents their natural electromagnetic resonance at 60 THz. In this work we present that is possible to change this value by covering it with a variable in thickness layer of gold. The analysis is performed by numerical simulations using COMSOL Multiphysics® software.

Laser anemometers based on application of Doppler Effect have been developed and are used in-flight, on aircrafts for measurement of air flow parameters, mainly its speed versus the airplane. The air speed measurements are vital for safe flights. The main basic idea of Doppler techniques consists in measuring the frequency of scattered light. In this paper, we propose a study of a laser Doppler ...
Modelling Ultra-short Pulse Laser Ablation of Dielectric Materials Using multiple Rate Equations - new

Ultrafast lasers are widely applied in micromachining, material science and physics. In industry, picosecond lasers are becoming more and more established. For pulse lengths shorter than the electron-phonon coupling time, heat affected zones are negligible. Thermally sensitive materials can be processed using ultrashort pulse laser radiation. Multi-component materials and poorly absorbing ...

In order to provide swift and precise diagnostics, physicians and medical doctors require an adequate amount of information about the patient\'s condition. An integrated SPR (surface plasmon resonance) biosensing platform is currently developed by our research group with the aim of preserving compatibility with microfabrication techniques, open-ended surface and integrated light source. In order ...

Photonic crystals are widely used in optical applications as waveguides and band filters. Filling the periodic structural material of photonic crystals with other materials is very useful in order to change the optical properties of the devices. In this paper electrostatic COMSOL simulations describing an electrospray deposition of particles in macroporous structures are performed.
Improving Detection Sensitivity for Nanoscale Targets Through Combined Photonic and Plasmonic Techniques
G. Zhang, Y. Zhao
Clemson University, Clemson, SC, USA
Photonic technique such as the whispering gallery mode (WGM) is often used for detection of small particles like bacteria and viruses. It offers good detection sensitivity and is advantageous over other detection techniques because the detection can be label free. However, the detection sensitivity may not be sufficient when the size of the detection target is in nanoscale. To change this, we ...

Low-dimensional semiconductor nanostructures, in which charge carriers are confined in a number of spatial dimensions, are the focus of much solid-state physics research, offering superior optical and electronic properties over their bulk counterparts. Both two-dimensional (2D) and zero-dimensional (0D) structures have seen wide-ranging applications in laser diodes, solar cells and LEDs to name ...

Phononic crystals are a class of materials that exhibit periodic variations in their density and elastic properties. Such crystals modify the propagation of acoustic waves and prohibit the propagation of sound for frequencies within the band gap. We discuss the simultaneous existence of phononic and photonic band gaps in a periodic array of silicon pillars deposited on a homogeneous SiO2 ...

The high power of X-ray beam delivered by synchrotrons and free electron lasers, up to 240 W/mm2, requires heat load management solutions to obtain the best performance from the optical elements which will shape the beam for its use in the experimental stations . One solution is the use of gas attenuators: a tube filled with an inert gas, usually Argon or Krypton, is placed between X-ray ...

A dielectric multilayer structure, with a grating profile on the surface layer, can couple light into a strongly confined surface wave, known as a Bloch surface wave. These surface modes can be used to design bio-sensors. The corrugated surface structure also enables azimuthal angular excitation of Bloch waves. In this paper, we exploit azimuthal interrogation to design highly sensitive Bloch ...
