“Infrared Nanophotonics based on Metal Antennas and Transmission Lines” NanoGUNE's first PhD Thesis defended by Martin Schnell

19/03/2012

Martin Schnell, Pre-doctoral researcher at the Nanooptics Group, got his Doctor Degree at the University of The Basque Country (UPV/EHU) after the defense of his thesis project last Monday 19 March. His research work achieved the maximum qualification (cum laude) after the defense and assessment of his work by an international committee that included leading researchers in the field of nanooptics. Dr. Schnell thesis project, done under the supervision of Rainer Hillenbrand, leader of the Nanooptics Group, has been the first thesis defended at nanoGUNE after the opening of the center in January 2009.

Nature Communications: Resolving the electromagnetic mechanism of surface-enhanced light scattering at single hot spots

21/02/2012

In a recent article (P. Alonso-González, et al., Nat. Commun. 3, 684) researchers from the nanooptics and the nanodevices groups at nanoGUNE provide experimental evidence that the intensity elastically scattered off the object scales with the fourth power of the local field enhancement provided by the antenna, and that the underlying electromagnetic mechanism is identical to the one commonly accepted in surface-enhanced Raman scattering.

Nanooptics article winner in the CeNS Publication Award 2011

06/12/2011

The article “Infrared-Spectroscopic Nanoimaging with a Thermal Source” a collaborative work between researchers of the nanooptics groups and Neaspec GmbH has been awarded the Publication Award 2011 from the Center for NanoScience in Munich for their work on near-field spectroscopy with a thermal source (more info). With this award, remarkably successful cooperation projects as well as outstanding research of an individual or research group are distinguished by CeNS.

SMALL: Plasmonic Nickel Nanoantennas

16/06/2011

In a recent article (J.Chen at al., Small, doi: 10.1002/smll.201100640) researchers from nanoGUNE have studied the fundamental optical properties of pure nickel nanoantennas. The article has been featured on the cover of the SMALL journal (Volume 7, Issue 16) and on the materials science news site Materials Views. “This study represents a step towards understanding and engineering magnetically controllable optical nanoantennas, which will be extremely useful for many developing technologies including biosensors, lasers, and solar cells”, says Richard Walters in his article “Nickel for Visible-Light Nanoantennas?”.

Nature Materials: Nano-FTIR – Nanoscale Infrared Spectroscopy with a Thermal Source

17/04/2011

Researchers from the nanoscience research center CIC nanoGUNE (San Sebastián, Spain) and Neaspec GmbH (Martinsried, Germany) have developed an instrument that allows for recording infrared spectra with a thermal source at a resolution that is 100 times better than in conventional infrared spectroscopy. In future, the technique could be applied for analyzing the local chemical composition and structure of nanoscale materials in polymer composites, semiconductor devices, minerals or biological tissue (F. Huth et al., Nature Materials 10, 352 (2011)).

Nature Photonics: Transmission Lines for Nanofocusing of Infrared Light

03/03/2011

A joint cooperation between three research groups at nanoGUNE reports an innovative method to focus infrared light with tapered transmission lines to nanometer-size dimensions. This device could trigger the development of novel chemical and biological sensing tools, including ultra-small infrared spectrometers and lab-on-a-chip integrated biosensors (Nature Photonics 5, 283–287, (2011) ).
