Teaser: Optical Antennas Book

13 Mars 2012 , Rédigé par JW Publié dans #Nanophotonics pick

A book reviewing all aspects of optical antennas is to be published this year (presumably?) by Cambridge University Press, edited by Andrea Alu and Mario Agio. For those interested in the specific configuration of aperture antennas, you may download a preprint copy of the chapter I wrote by clicking here (for individual non-commercial use only of course).

Chapter contents:

- Enhanced light-matter interaction on nanoaperture antennas (single, corrugated and arrays)

- Biophotonic applications of nanoaperture antennas

- Nanophotonic applications of nanoaperture antennas

Just got back from the frontiers of engineering symposium held end February in Kyoto Japan. Very positive impression of both Japan and conference.

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!

80 years later... JW in Edouard Branly's office, after the Branly prize award.


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.
