Optical resonances based-sensors in planar configuration

Share

Abstract: The two most used optical resonances for the fabrication of sensors are those based on surface plasmons (SPR) and those based on lossy modes (LMR).

In the late sixties, optical excitation of surface plasmons by means of attenuated total reflection was demonstrated by Kretschmann and Raether and Otto. In 1980, Pharmacia became interested in SPR and began investigating the possibilities of the technique and in 1984, founded the company Pharmacia Biosensor AB. SPR based sensors are expected to reach in 2025 a business of far more than 1 billion dollars.

More recently, LMR technique has emerged as an alternative platform to SPR. Although both SPRs and LMRs were theoretically already known, unlike SPR-based sensors, it was not until 2009 that the first LMR-based sensor was published. Taking into account the increasing number of research groups all around the world that are working on this LMR technology, high impact results will be very likely obtain due to the extremely high sensitivity of the sensors and devices developed as well as its enormous simplicity and low cost. The number of articles published on LMR increases year after year. There are also currently a number of initiatives to create companies using this technology.

Finally, a work has just been published using surface exciton polariton resonances (SEPR) that completes the trilogy of optical resonances that are based on a substrate and a thin-film that generates the resonances and the sample to be analysed. The requirements of the materials to generate the respective resonances in the three mentioned cases (SPR, LMR and SEPR) are different but their final applications and modus operandi are similar.

Biography:

Biography: Ignacio R. Matias received the M.S. degree in Telecommunications Engineering and his Ph.D. degree in Telecommunications from the Polytechnic University of Madrid (UPM), Madrid, Spain, in 1992 and 1996, respectively. He is married with 4 children. In July 1996 Ignacio R. Matias received the UPM extraordinary prize to the best doctoral thesis of the year 1996-97. In 1998 he became Lecture in the Department of Electrical, Electronics and Communications Engineering (DIEEC) at the Public University of Navarra (UPNA); and from October 2006 he is Professor of DIEEC at UPNA.

Ignacio R. Matias has participated in more than 120 research projects with both public and private funding. As a result of these works he has obtained 16 patents and 6 copyrights. Regarding transfer to the industry, he has been founding partner of six spin-off companies. He has published more than 250 papers in international research journals high impact. In addition, we have been accepted about 275 works at international conferences of prestige (17 of which were invited). He also is the author of 7 books and 21 international scientific chapters in different books.

As for academic positions he has had, mentioning that he has been Deputy Director from 1999 to 2006 and Director from 2009 to September 2014 to the School of “Industrial, Computer Sciences and Telecommunications Engineering” at the Public University of Navarra. From 2014 to 2017, he has been the Director of the Research Institute of the Public University of Navarra, Institute of Smart Cities (ISC). In 2017 he became the TEC (electronic and communications technology) Coordinator of the AEI (Spanish Research Agency). Presently, he is the President of the Spanish Agency for Quality Assessment and Accreditation (ANECA) Claims Committee.
