Modeling Nanowire Photovoltaic Devices

D. P. Wilson1, R. R. LaPierre1
1Department of Engineering Physics, McMaster University, Hamilton, Ontario, Canada

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 ... 詳細を見る

Design of a Surface Plasmon Resonance Based S-R Latch Circuit

A. O. Silva1, M. G. L. Moura1
1Federal Center for Technological Education of Rio de Janeiro, State of Rio de Janeiro, Rio de Janeiro, Brazil

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 ... 詳細を見る

Solving the Paraxial Wave Equation

S. Avramov-Zamurovic1, K. Jung1, R. M. Madani1
1United States Naval Academy, Annapolis, MD, USA

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 ... 詳細を見る

S. Saha1, N. Kinsey1
1Virginia Commonwealth University, Richmond, VA, USA

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 ... 詳細を見る

Acoustic Metamaterial Lens and Simulation-Based “Meta-Library”

R. Grey1, N. Routhier1, E. Walters1, N. Kinsey1, U. Ozgur1
1Virginia Commonwealth University, Richmond, VA, USA

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, ... 詳細を見る

Simulation of Sidewall Scattering Losses for Light Pipes

C. Madsen1
1Texas A&M University, College Station, TX, USA

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 ... 詳細を見る
