[Illinois] Using Photonic Crystals to Enhance SERS Signals for Early Detection of Prostate Cancer
Online Presentations | 29 Jan 2016 | Contributor(s):: Caitlin Race
Prostate cancer is the second most common cancer for men, and the second leading cause of death due to cancer in men. Currently, the most common screening method aims to detect high levels of prostate-specific antigen (PSA) in blood. Our research has shown the potential for both better prostate...

Atom-photon Interactions In 1D Photonic Crystals: From cQED to band-gap physics
Online Presentations | 05 Jan 2016 | Contributor(s):: Jonathan Hood
We investigate opportunities that emerge from the integration of cold atoms with nanoscopic photonic crystal waveguides (PCWs). PCWs enable the light-matter interaction to be engineered for both trapping and strong atom-photon coupling, thereby opening new avenues for novel quantum transport and...

Three-Dimensional Photonic Crystals
Online Presentations | 11 Feb 2008 | Contributor(s):: Minghao Qi
A photonic crystal (PhCs) is typically a composite of a high-dielectric-constant material (e.g. Si) and a low-constant one (e.g. SiO2 or air), arranged periodically in space. Two dimensional examples include a hexagonal lattice of air holes drilled in a Si slab, or a set of Si rods at square...
