A Comparison of Mass Reduction Methods for Silicon-on-Oxide (SOI)-based Micromirrors

H. J. Hall [1], L. A. Starman [1],
[1] Sensors Directorate, Air Force Research Laboratory, Wright-Patterson AFB, OH, USA

Beam steering and adaptive optics micromirror applications commonly demand optically flat surfaces with minimal mass. When reflective coatings (usually metallic Au or Al) are applied to micromirror surfaces in order to meet optical reflectivity requirements the resulting film stress ... 詳細を見る

Thermal-Optical Modeling of a Signal Enhancement Approach for Paper-Based Diagnostics

D. Gasperino [1]
[1] Intellectual Ventures Laboratory, Bellevue, WA, USA

INTRODUCTION: Point of care diagnostics aimed at low-resource settings need to be relatively simple, robust and low-cost. The most commonly-used diagnostic platform in these settings is the lateral flow assay (LFA). LFAs are paper-based immunoassays designed to perform on-strip binding ... 詳細を見る

Introduction: Single-photon detectors capable of ensuring high fidelity read-out of quantum information delivered via photons of specific polarization are crucial in QIP [1]. Our previous studies have shown that different types of one dimensional plasmonic structures enhance the ... 詳細を見る

Plasmonic Waveguide Analysis

K. C. Koppenhoefer [1], S. Yushanov [1], J. S. Crompton [1],
[1] AltaSim Technologies, Columbus, OH, USA

Surface Plasmons (SP) or Surface Plasmon Polaritons (SPP) are electromagnetic excitations that propagate at the interface between a dielectric and a conductor, and are evanescently confined in the perpendicular direction to the propagation. They arise via coupling of the electromagnetic ... 詳細を見る

Analysis of a Plasma-Mediated Photoacoustic Response From Plasmonic Nanoparticles in Ultrashort Regime

A. Hatef [1], B. Darvish [1], A. Dagallier [2], C. Boutopoulos [2], M. Meunier [2],
[1] Nipissing University, North Bay, ON, Canada
[2] École Polytechnique de Montréal, Montréal, QC, Canada

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 [1]. Such functionality is due to the localized surface plasmon resonance (LSPR) ... 詳細を見る

Simulating Plasmon Effects in Nano-Structured OLED Cathodes Using COMSOL Multiphysics® Software

L. Wang [1],
[1] Konica Minolta Laboratory USA, Inc., San Mateo, CA, USA

Organic light emitting diode (OLED) is an emerging technology for next-generation flat panel display and solid-state area lighting thanks to its many advantages such as light weight, low operating voltage, and flexibility, etc. A typical OLED has a multilayer structure that includes a ... 詳細を見る

Coupling Picosecond Terahertz Pulses to a Scanning Tunneling Microscope

[1] Pennsylvania State University, University Park, PA, USA

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 ... 詳細を見る

Simulation of Vector Mode Grating Coupler Interfaces for Integrated Optics

C. T. Nadovich [1],
[1] Lafayette College, Easton, PA, USA

The use of grating couplers to couple conventionally phased and polarized light near vertically in and out of optical slab or film waveguides [1] represents an attractive method to interface optical fiber to photonic ICs. Previously developed grating coupler designs use transversely ... 詳細を見る

Low Cost All Optical Swept Source for Optical Communication Applications

J. T. Andrews[1], S. Chaurasiya[1], O. P. Chaudhary[1], D. Agarwal[1]
[1]National MEMS Design, Department of Applied Physics, Shri G S Institute of Technology & Science, Indore Madhya Pradesh, India

By introducing a periodic modulation in a waveguide, it is possible to create an interaction between forward-traveling and backward-traveling modes of an optical waveguide. Bragg grating may be a one dimensional diffraction grating which diffracts light from the forward-traveling mode ... 詳細を見る
