Glass-based Photonic Structures: Advances and Perspectives

Maurizio Ferrari
Istituto di Fotonica e Nanotecnologie (CNR-IFN)
Italy
 

Brief Bio
Maurizio Ferrari, physicist, is research director at the Institute of Photonics and Nanotechnologies (IFN) of the National Research Council (CNR) in Trento. He has been prime investigator or key researcher in many national and international projects. He has 256 scientific articles on international journals (ISI-JCR), 214 papers in proceedings of national and international conferences, 450 communication at national and international congress, and several other publications and book chapters (h-index: 34). His main areas of research include: glass photonics; glasses obtained by melting and by sol-gel route activated by rare-earth ions and chromophores; planar waveguides obtained by different techniques (dip-coating, spin-coating rf-sputtering, ionic-exchange), both passive and active; nanostructured, composite and nano phase materials; confined optical structures (photonic crystals, microcavities, and microresonators); applications to sensing and energy. He has been program chair or member of scientific and program committees of many national and international conferences. He was co-founder of the PRE Workshops series and will be co-chair of PRE'17 in Rome in November 2017.


Abstract
Glass photonics is pervasive in a huge number of human activities and drive the research in the field of enabling technologies. Glass materials and photonic structures are the cornerstones of scientific and technological building in integrated optics. Photonic glasses, optical glass waveguides, planar light integrated circuits, waveguide gratings and arrays, functionalized waveguides, photonic crystal heterostructures, and hybrid microresonators are some examples of glass-based integrated optical devices that play a significant role in optical communication, sensing, biophotonics, processing, and computing. We present some recent results obtained by our consortium in rare earth doped photonic glasses and confined structures, in order to give some highlights regarding the state of art in glass photonics. To evidence the unique properties of transparent glass ceramics we will compare spectroscopic and structural properties between the parent glass and the glass ceramics. Starting from planar waveguides we will move to spherical microresonators, a very interesting class of photonic confined structures. Then we will present 1D-potonic crystals and opals allowing management of optical and spectroscopic properties. We will conclude the short review with some remarks about the more significant applications such as laser action and structural sensing and the appealing perspective for glass-based photonic structures.



 

 

The Physics and Technology of Metadevices and Metasystems

Kevin MacDonald
Optoelectronics Research Centre, University of Southampton
United Kingdom
 

Brief Bio
Dr. MacDonald is a Principal Research Fellow with the Optoelectronics Research Centre’s Nanophotonics & Metamaterials Group, and Manager of the University’s Centre for Photonic Metamaterials.  He received MPhys and PhD degrees from the University of Southampton’s School of Physics and Astronomy and joined the school as a research fellow in 2001, before moving to the Optoelectronics Research Centre in 2006. His research interests lie in the fields of phase-change and electron-beam nanophotonics, as well as active/adaptive, all-dielectric and optomechanical metamaterials. He has published 60 peer-reviewed journal articles on these subjects and over 190 conference papers including more than 60 keynote or invited talks. He is a member of the Quantum Electronics & Photonics Group Steering Committee for the UK’s Institute of Physics, an editorial board member for the Nature Publishing Group journal Scientific Reports, and co-chair of the Metamaterials conference at SPIE Photonics Europe.


Abstract
Photonic metamaterials research has migrated in recent years from the study of almost exclusively plasmonic metal nanostructures to embrace a variety of advanced material platforms, including dielectrics, semiconductors, superconductors, phase-change media, and topological insulators. Optically- and electronically-actuated reconfigurable photonic metasurfaces based on such materials offer a range of low-loss, nonlinear, tuneable and switchable optical functionalities in ultra-compact form-factor – for example, engaging nano(opto)mechanical or phase-change response mechanisms to serve signal modulation, spectral/polarization selection or dispersion manipulation applications. In this talk I will review recent developments in the field, ranging from the demonstration of compositionally-tuneable plasmonic properties in chalcogenides to the integration of active all-dielectric and plasmonic metamaterials with optical fibre waveguides.
