WASHINGTON, Sept. 22 Light-matter interaction at the nanometer scale has turned into a very fast-growing field of research known as nano-optics. To highlight breakthroughs in the specific areas of nano-optics known as nanoplasmonics and metamaterials, the editors of the Optical Society's (OSA) open-access journal Optical Materials Express (OMEx) have published a special Focus Issue on Nanoplasmonics and Metamaterials (http://www.opticsinfobase.org/ome/virtual_issue.cfm?vid=145). The issue is organized and edited by Guest Editor Romain Quidant of the Institute of Photonic Sciences and the Catalan Institute for Research in Advanced Studies, Spain, and OMEx Associate Editor Vladimir Drachev of Purdue University, USA.
"Research in nanoplasmonics and metamaterials is very well representative of the tremendous increase of activities in nano-optics," said Drachev. "Both are expected to have a strong impact on our society, especially in the areas of chip-scale and high-integration density optical interconnects, advanced materials for photovoltaics, and bio-medical applications."
The first main motivation behind such enthusiasm for nano-optics comes from the potential of the field to extend concepts and functionalities of conventional optics down to the nanometer scale; toward ultra-compact photonic devices that are not limited by diffraction. Beyond miniaturization, an additional motivation arises from the rich new physics involved when matter is downsized to dimensions that are much smaller than the light wavelength.
"At this very exiting stage of research in nanoplasmonics and metamaterials, further advances are in part conditioned by the development of new optical materials with improved properties, as well as advances in nanofabrication techniques to increase the quality of constitutive nano-units," said Quidant. "We have seen a noteworthy advance in materi
