Latest article: how to enlarge your plasmonic enhancement factor

20 Février 2012 , Rédigé par JW Publié dans #Recent research work

Recently released in International Journal of Optics, this study describes how to show enlarged values of fluorescence enhancement factor using optical (plasmonic) antennas without changing the antenna design. The discussion here focuses on the influence of excitation intensity, reference quantum yield and collection efficiency. Some general formulas are given, which should help avoid some confusions.

To my knowledge, this is also the first reference of Didier Wampas in a research article. Enjoy!

See the funny detail in the painting by Branly's daughter, you can see Branly taking Zeus lightnings

Edouard Branly's intruments have been collected in his old laboratory and office, which is now a small museum located in the Institut Superieur d'Electronique de Paris ISEP. If you pass by, the visit is interesting, especially the Faraday's cage room all covered by copper.

Key benefits from Fresnel - Marseille:

* ambitious innovative research, projects were selected by most prestigious national and european grants.

* state-of-the-art equipment resources & know-how

* close mentorship from a senior CNRS researcher

* long-term career visibility, contracts have several years duration

* full social advantages from being employed by French CNRS

* South France quality of life: sun, see, mountains & food

 

Positions filled:

DONE PhD ExtendFRET : Extended fluorescence energy transfer with nanophotonics

DONE PhD Twins : Theoretical / numerical research in plasmonics and optical antennas

DONE PostDoc ExtendFRET : Plasmonic circuits design & simulations

DONE PostDoc Twins : Design of optical antennas for enhancing light-matter interaction at the nanometer scale

DONE PostDoc NanoVista : Enhanced detection of single fluorescent molecules with plasmonic antennas
