Nanowire Photonic Systems

: Advances in materials and the understanding of the behavior of materials arc critical to future Air force and DoD technologies, ranging from sensing, imaging and threat detection to information processing and storage. In each of these critical areas. there is the potential to make quantum jumps forward in capabilities by developing and exploiting the broad area of science and technology known as nanotechnology. Hence, the development of new nanoscale structures with the unique properties and fabrication of hybrid structures and systems that exploit these unique capabilities and those of conventional technology could lead to systems that are essential to and create powerful new technology. This project has addressed key scientific issues underlying the development of nanowire building blocks and their development in a variety nanophotonic devices. including nanoseale detectors with ultra-high sensitivity and sub-wavelength spatial resolution. no\el nanoscale photovoltaic devices with high efficiencies and capabilily of powering nanoelectronic devices. and nanoseale light sources. including nanolasers.
