We present a novel approach for mapping the radiative and non-radiative local density of states in the near-field of a nanostructure by using a fluorescent near-field probe. Experiments are in quantitative agreement with numerical simulations.
In this work we investigate the use of Au nanorods as optically actuated electron emitter arrays. We have fabricated high-density arrays of 10 nm diameter Au nanorods via electron beam lithography and studied the effects of, emitter array density on charge yield, and laser intensity on emitter morphology, respectively. Additionally, we have numerically simulated the magnitude of the local electric...
Here we report on the generation and engineering of polarized emission from aligned hybrid gold nanorods embedded in a Polyvinyl Alcohol film, where circularly polarized input light can be converted into broadband linearly polarized emission.
The strong coupling between excitons and surface plasmon polaritons (SPP) in metal-semiconductor and metal-dye nanostructures are interesting because in analogy to semiconductor microcavities may be of importance in designing novel nano-optic devices. So far, however, very little is known about such nonlinearities and rather weak effects have been observed. This paper reports on the first observation...
We report novel methods to enhance light emission efficiencies from InGaN/GaN quantum wells (QWs) based on nanophotonics and plasmonics. First, the nanoscopic optical properties were observed and characterized based on the carrier localization and the quantum confinement Stark effect depending on the In composition of InGaN. Based on the results, we proposed that the emission efficiencies should be...
