Plasmonics and Metamaterials at CLEO/Europe EQEC 2015 Conference

24 Octobre 2014 , Rédigé par JW

Paper submission is open to join the next CLEO/Europe-EQEC conference at Munich in June 2015. The CLEO/Europe-EQEC conference series has a strong tradition as a comprehensive and prestigious gathering of optics and photonics researchers and engineers in Europe.


Plasmonics and metamaterials are specially highlighted by a dedicated topical meeting, see EQEC 2015 topic EH Plasmonics and Metamaterials. Metal nanophotonics from fundamentals towards applications and including all spectral regimes: plasmonic nanostructures, antennas, cavities and waveguides; metamaterials; hybrid materials; nonlinear structures and effects; active systems, systems with gain.

Multi-focus FCS with photonic nanojets arrays

2 Octobre 2014 , Rédigé par JW Publié dans #Recent research work

Our article “Multi-focus parallel detection of fluorescent molecules at picomolar concentration with photonic nanojets arrays” has just been released in Applied Physics Letters. We replace the complex microscope objective commonly used in fluorescence sensing by an array of latex microspheres. This realizes a novel regime where several focal spots are illuminated to detect the possible presence of a fluorescent molecule in one of them. A detailed theoretical description of the phenomen is provided along with experimental demonstration.
This work describes an efficient disposable lens element that enables single molecule sensitivity at low picomolar concentration. The simplicity of the design makes it perfect for integration in portable microfluidic readers.
