New tool for non-invasive quality control of graphene devices


Researchers from the Nanooptics group at CIC nanoGUNE in collaboration with colleagues at ICFO - The Institute of Photonic Sciences (Catalunya) developed a new non-invasive room-temperature technique for graphene device characterization. This work has been funded by the EC Graphene Flagship and was recently reported in Nature Communications.

Tracking slow nanolight in natural hyperbolic metamaterial slabs

Measured dispersion (energy versus momentum diagram) of hyperbolic phonon polaritons in boron nitride.

Researchers from the Nanooptics and the Nanodevices groups at CIC nanoGUNE (Basque Country) in collaboration with colleagues at ICFO - The Institute of Photonic Sciences (Catalunya) have imaged how light moves inside an exotic class of matter known as hyperbolic materials. They observed, for the first time, ultraslow pulse propagation and backward propagating waves in deep subwavelength-scale thick slabs of boron nitride – a natural hyperbolic material for infrared light. This work has been funded by the EC Graphene Flagship and was recently reported in Nature Photonics and highlighted as a News&Views.

Florian Huth, Pre-doctoral Researcher at the Nanooptics Group at nanoGUNE, receives his PhD at the University of the Basque Country (UPV/EHU) after the defense of his thesis project on Monday 25 May 2015. Hir research work, entitled Nanoscale Infrared Near-Field Spectroscopy", has been developed under the supervision of the Nanooptics Group Leader and Ikerbasque Research Professor Dr. Rainer Hillenbrand.

Pablo Alonso-González, Winner of the RSEF-BBVA Foundation 2014 prize


The nanoGUNE researcher Pablo Alonso-González has been awarded the RSEF-BBVA Foundation 2014 prize for Physics in the New Researchers in Experimental Physics category. Alonso-González works in this center’s Nanooptics group in Donostia-San Sebastian and his research is currently focussing on the optical properties of graphene at the nanoscale. The researcher was the first to obtain guided light imaging in this material with nanometric precision, and his work was published by the journal Nature.

Nature Materials: Graphene plasmons go ballistic


Squeezing light into tiny circuits and controlling its flow electrically is a holy grail that has become a realistic scenario thanks to the discovery of graphene. This tantalizing goal is realized by exploiting so-called plasmons, in which electrons and light move together as one coherent wave. Plasmons guided by graphene -a two-dimensional sheet of carbon atoms – are remarkable as they can be confined to length scales of nanometers, one to two hundred times below the wavelength of light. However, until now these plasmons were found to rapidly lose energy, limiting the range over which they could travel.

Science: Flatland optics with graphene


Researchers from nanoGUNE, in collaboration with ICFO and Graphenea, introduce a platform technology based on optical antennas for trapping and controlling light with the one-atom-thick material graphene. The experiments show that the dramatically squeezed graphene-guided light can be focused and bent, following the fundamental principles of conventional optics. The work, published yesterday in Science, opens new opportunities for smaller and faster photonic devices and circuits.

Infrared sheds light on single protein complexes


Researchers from the nanoscience research center CIC nanoGUNE, the Freie Universität Berlin and Neaspec company employ nano-FTIR spectroscopy for label-free chemical and structural imaging of proteins with nanoscale spatial resolution and with sensitivity to single protein complexes of less than one attogram (10-18 gram). The work has been published recently in Nature Communications. (I. Amenabar et al., Nature Communications, 2013, DOI:10.1038/ncomms3890)

Journal of Optics: Special issue on graphene nanophotonics
