Flickr2013 SPIE Intweviews George Wang: Developing next-generation lighting using nanowires January 14, 2013 George Wang, a senior investigator in the SSLS, was interviewed about his work in the EFRC on nanowire growth and the possibility of achieving ultra-efficient solid-state lighting. You may view his interview at: http://spie.org/x91938.xml “Solid-state Lighting: ‘The case’ 10 Years After and Future Prospects” paper [...]

Research Challenge 6: Beyond Spontaneous Emission Reflectivity data from a GaN microcavity showing anti-crossing behavior and strong coupling. This Research Challenge explores radiative processes that go beyond incoherent emission. For example, although light-emitting diodes (based on spontaneously-emitted incoherent light) are presently thought of as the source of choice for white light generation. However, coherent light [...]
Research Challenge 5: Enhanced Spontaneous Emission (a) Core/shell nanoparticle geometry: (b) A cross section of the optical intensity distribution around the core/shell nanoparticle. (c,d) Internal optical intensity enhancement as a function of core radius and thickness when the size-dependent values of the metal’s dielectric functions are used. c) Au, d) Ag shells. Our explorations focus [...]
