When optical components are reduced to the nanoscale, they exhibit interesting properties that can be harnessed to create new devices. For example, imagine a block of material with thin layers of alternating materials. This creates a periodic arrangement of alternating dielectric constants, forming a "photonic crystal" that is analogous to the electronic crystals used in semiconductor devices. Photonic crystals, along with quantum dots and other devices patterned at the nanoscale, may form the basis for sensors and switches used in computers and telecommunications.

GaN is a wide bandgap material which can on one hand withstand high power and high temperature operating conditions, and on the other hand has high saturation velocity needed for high frequency operation. This tremendous potential has not been fully realized yet and in this talk it will be shown...
Negative Refraction, Wave-particle Dualism and “Minkowski-Abraham controversy”
19 Nov 2012 | | Contributor(s):: Victor G. Veselago
Professor Veselago was the first to identify that the relationships between energy and linear momentum are significantly different for electromagnetic radiation and material particles. The process of transfer of radiation from the emitter to the receiver will be discussed. It is shown that the...
Nanophotonics with Metamaterials
27 Aug 2012 | | Contributor(s):: Vladimir M. Shalaev
One of the most unique properties of light is that it can package information into a signal of zero mass and propagate it at the ultimate speed. It is, however, a daunting challenge to bring photonic devices to the nanometer scale because of the fundamental diffraction limit. Metamaterials can...
