Linear and Nonlinear Optical Devices Based on Slow Light Propagation: Figures of Merit
Performance of optical delay lines and nonlinear devices based on slow wave propagation in photonic crystal waveguides in the presence of higher order dispersion is analyzed and compared with other slow light schemes, such as coupled resonators, media with electromagnetically-induced…

Plasmonic Metamaterials: Unusual Optics and Applications
Surface plasmon-polaritons (or plasmons) are collective excitations of the conduction electrons and the electromagnetic field on the surface of such good metals as gold and silver. Near the frequency of surface plasmon resonance plasmons may perceive regular dielectrics as negative index...

Silicon Photonics: Opportunity Challenges and Recent Results
The silicon chip has been the mainstay of the electronics industry for the last 40 years and has revolutionized the way the world operates. Today a silicon chip the size of a fingernail contains nearly one billion transistors and has the computing power that only a decade ago would take up an...

Routing Light with Nematicons: Light Localization and Steering in Liquid Crystals
Nematic liquid crystals support optical spatial solitons via light-induced molecular reorientation. Such all-optical waveguides can channel a signal towards a destination, hence permitting signal routing. Owing to the inherent anisotropy of nematic liquid crystals, molecular orientation and...

Surprises on the nanoscale: Plasmonic waves that travel backward and spin birefringence without magnetic fields
As nanonphotonics and nanoelectronics are pushed down towards the molecular scale, interesting effects emerge. We discuss how birefringence (different propagation of two polarizations) is manifested and could be useful in the future for two systems: coherent plasmonic transport of near-field…

Plasmon-resonant Nanorods as Multifunctional Imaging Agents
Gold nanorods have several outstanding characteristics as optical contrastagents for biomedical imaging. Their strong optical absorption atnear-infrared (NIR) frequencies can be used to generate contrast for opticalcoherence tomography (OCT) imaging, and is well matched for detectionmodalities...
