Aitor Villafranca Velasco received the Young Researcher Award
Monday, 28 May 2012 12:25
Aitor V. Velasco has received the Young Researcher Award at the X National Meeting of Optics, Spanish Optical Society (SEDOPTICA), for his work “Spatial Heterodyne Fourier-Transform Spectrometer Implemented With Silicon Wire Spiral Waveguides,” that will be presented in a plenary session September 4th, 2012 in Zaragoza (Spain).
The paper discloses the design, fabrication and characterization of a Fourier Transform Spectrometer [1] which comprises an array of 32 Mach-Zehnder interferometers with increasing optical path differences between arms across the array (see photograph below). A wavelength resolution of 0.1 nm is achieved within a free spectral range of 1.6 nm. Spiral Si-wire waveguides are used in the arms of the interferometers in order to reduce the footprint of the device to less than 12 mm2.

Wednesday, 16 December 2009 14:39
José A. Rodrigo, member of GICO-UCM and former PhD student has received the distinction for the best PhD Dissertation in Faculty of Physics of the Complutense University of Madrid.
The title of the thesis is "First-order optical systems in information processing and optronic devices" and can be found in this link.
The PhD thesis was selected by the Jury among a total of twenty five dissertations presented at the Faculty of Physics during the year 2008.
We congratulate José, who is now with a Juan de la Cierva contract at the Instituto de Óptica "Daza de Valdes", CSIC, Madrid.
