Photonic Metamaterials: From Linear to Nonlinear Optics
14 Dec 2010   Contributor(s):: Natalia Litchinitser
Metamaterials open unparalleled opportunities for "engineering" previously inaccessible values of refractive indices from positive to nearzero and even negative values, and new avenues for light manipulation. While an enormous progress has been made in the field of linear optics of uniform...

Illinois iOptics Lecture 5: Deposited Nanorod Films for Biosensor Applications
17 May 2010   Contributor(s):: Brian Cunningham
Planar photonic crystals have been used as the basis of many biological sensing devices. Here, we successfully demonstrated that the combination of a photonic crystal structure and a dielectric nanorod coating prepared by the glancing angle deposition technique can lead to significant increases...

Experiment vs. Modelling: What's the problem?
10 Aug 2009   Contributor(s):: William L. Barnes
Progress in plasmonics has been greatly assisted by developments in experimental techniques and in numerical modelling. This talk will look at some of the difficulties that emerge when comparisons are made between experiment and theory. Through the use of four examples I will illustrate what...
