Over the last decade, plasmonic nanoparticles (PNPs) have received growing interest as exogenous contrast agents in the thermal expansion based photoacoustic (PA) imaging technique in biomedical applications . Such functionality is due to the localized surface plasmon resonance (LSPR) created by the light-induced coherent oscillation of the conduction electrons in the PNPs. In the near-field ...

The Complementary Metal-Oxide-Semiconductor (CMOS) technology is a gateway to fabricating low cost electronic and photonic components to date. The Silicon-based nanophotonics platform leverages CMOS technology to fuel the effort to provide increasingly high-speed and high-bandwidth devices at low costs in response to global demands in telecommunication infrastructure. The current industry ...

A program for self-consistent modeling of electron-hole energy spectrum and space-charge distribution in III-nitride based quantum well (QW) structures has been developed. The model takes into consideration full 6-band description of the valence band states, nonparabolicity of the electron spectrum, quantum confinement of electrons and holes, strain induced modifications of the band structure, ...

Ever since its advent optical fibers have revolutionized the communication technology but apart from communication they are being used in a variety of other areas such as medical technology, sensing, laser sources in the form of fiber lasers, amplifiers, cutting and drilling, defense applications etc. Optical fibers are manufactured by drawing techniques which have largely limited the materials ...

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 ...

A patch antenna based on metamaterials of composite split-ring-resonators (CSRRs) and strip gaps is designed with COMSOL Multiphysics® software. The antenna is constructed by using CSRR structures in forms of circular rings on the patch and employing strip gaps on the ground plane. The signal is fed by a common microstrip line that connects the patch and the input port. The antenna is based on a ...

In thin-film solar cells (a-Si:H, µc-Si:H, CIGS, etc.) scattering of light is very important to increase absorption of light in the active layers of solar cells. Today the most efficient thin-film solar cells are designed or deposited on random textured transparent conductive oxides (TCO). In order to study the scattering properties of the surface texture we have developed a numerical model in ...

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.

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 ...

Introduction: Single-photon detectors capable of ensuring high fidelity read-out of quantum information delivered via photons of specific polarization are crucial in QIP . Our previous studies have shown that different types of one dimensional plasmonic structures enhance the absorptance of p-polarized light [2, 3]. The purpose of present study was to optimize four different types of ...
