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 ...

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.

It is well-known that metal nanoparticles (NPs) excited at the plasmon frequency not only exhibit peculiar optical properties (e.g., a peak in the extinction spectrum, an enhanced electromagnetic near-filed) but also heat up . This phenomenon is highly investigated for medical applications, but it can be exploited also for the realization of optical devices. In our study we use COMSOL ...

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 ...

Nearly seven lakh Indians die of cancer, while over 10 lakh are newly diagnosed with some form of the disease every year. Surgical resection is not always feasible in patients with hepatocellular carcinoma. Microwave Coagulation Therapy (MCT) has been used as an alternative to resection and its efficiency has been evaluated in tissue microwave irradiation from a dipole antenna causes water ...

Surface Plasmon Polaritions (SPPs), as electromagnetic waves localized at the surface of a metal, enjoy the unique properties to confine energy into sub-wavelength scale, which is beneficial for future photonic integration. However, the severe absorption caused by the metal influences the propagation distance greatly. Actually, SPPs loss can be compensated by optical parametric amplification in ...

Adaptive optics control using liquid filled membrane lens is based on the principle of deflection of polymeric membrane. Controlled deflection in membrane leads to controlled focal length. This enhances the focus tuning ability of the system at the same time make optical system compact and economical. The adjustment of fluid pressure helps to toggle between different field of view at the same ...

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 ...

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 ...
Improving Detection Sensitivity for Nanoscale Targets Through Combined Photonic and Plasmonic Techniques

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 ...
