Modeling Nanowire Photovoltaic Devices
Introducing nanostructures into conventional III-V solar materials can improve the light capturing ability of solar devices. Nanowires are thin columns light absorbing material with such a small footprint that they can be grown epitaxially on lattice mismatched substrates. By growing III ... Read More
Design of a Surface Plasmon Resonance Based S-R Latch Circuit
Surface plasmon polaritons are electromagnetic modes excited at the conducting-dielectric interface owing to the resonant interaction between incident photons and free electrons at the conducting surface. Plasmonic resonances confine optical power at subwavelength scales, which allows ... Read More
Solving the Paraxial Wave Equation
We will present a study of our attempt to solve the Paraxial Wave Equation to simulate propagation of various laser beams in vacuum as well as in a turbulent medium. Our approach is to explore the suite of partial differential equation solvers in COMSOL® and cast our problem as an ... Read More
Modeling On-Chip Nanoscale Trap and Enhance Device for Quantum Photonics Using COMSOL Multiphysics®
In recent years, with the rise of quantum optical technologies, there has been a spurring research interest growing on single-photon emitters (SPE). To date, the focus in engineering improved SPE has been mainly towards better enhancement overlooking the tenuous manufacturing process ... Read More
Acoustic Metamaterial Lens and Simulation-Based “Meta-Library”
Metamaterials are composites of subwavelength structures that can be engineered to affect the propagation of a wave in specific ways as it travels through the material. While metamaterials can be used with any type of wave, they are most commonly found in electromagnetic waves. However, ... Read More
Simulation of Sidewall Scattering Losses for Light Pipes
The impact of surface roughness on the optical transmission of light pipes has been addressed using a geometric optics approximation (GOA); however, there has not been a comparison between the GOA and a wave optics solution to evaluate the relative impact of diffraction effects on the ... Read More
Self-Consistent Calculation of Exciton Binding Energy in Quantum Structures with Rotational Symmetry
An exciton is a quasiparticle forming in semiconductors when an electron is excited from the valence band into the conduction band, leaving a positive hole behind. Due to the Coulomb interaction between opposite charge particles, the exciton has slightly less energy than the unbound ... Read More
Inverse-Design in Large Photonic Gratings Enabling Efficient Photonic-to-Free-Space Mode Coupling
Realization of an efficient coupling between photonic sub-micrometer size modes and hundred micrometer wide free-space beams remains a main engineering hurdle to a wider acceptance of miniaturized chip-scale atomic and bio systems. The major obstacle comes from a gigantic mode mismatch ... Read More
