Exploring the vibrations of objects at the nanoscale

A special session on Nanophonics and Nanomechanics, organized by Dr Pedro David Garcia from the ICN2 and Dr. Daniel Lanzillotti-Kimura from the Centre de Nanosciences et de Nanostructures - CNRS (France), was held at META 2019 – Lisbon to discuss recent development of this research field.

From July 23 – 26 July, the 10th edition of the International Conference on Metamaterials, Photonic Crystals and Plasmonics (META) took place at the Instituto Superior Técnico in Lisbon, (Portugal). A special session on nanophotonics and nanomechanics was organized by Dr. Pedro David García Fernandez of the ICN2 Phononic and Photonic Nanostructures group and Dr. Daniel Lanzilotti-Kimura from the CNRS (France).

Phonon engineering at the nanoscale enables the control of interactions of acoustic vibrations with other excitations in solids and can be used for applications in optomechanics, material characterization, thermal transport and in the study of fundamental localization phenomena. In this session, a broad spectrum of fields was covered in which the phonon engineering unlocks a new control knob.

The topics discussed in the session ranged from phonons in nanostructures, cavity optomechanics, nanomechanics, topological effects in phononic systems, Brillouin and Raman scattering, thermal transport, phononic localization phenomena, coupling of mechanical vibrations to other degrees of freedom and acousto-plasmonics. Among the renowned international invited speakers were Prof. Ivan Favero (Universite Paris Diderot, France), Prof. Bernard Perrin (Sorbonne Universités, France), Prof. Ilaria Zardo (University of Basel, Switzerland), Dr. Sebastian Volz (CNRS, France-Tokio), Dr. Klaas-Jan Tielrooij (Catalan Institute of Nanoscience and Nanotechnology, Spain) or Dr. Ewold Verhagen (AMOLF, The Netherlands)

The META Conference provides an international forum for discussion on various current hot topics such as metasurfaces & metadevices, topological effects in optics, two-dimensional materials, light-matter interaction in nanocavities, plasmonic circuits, thermal engineering, quantum photonic systems, etc. Featuring several plenary talks by experts like Prof. Federico Capasso (Harvard University, USA), Prof. Nader Engheta (University of Pennsylvania, USA) and Prof. Eli Yablonovitch (University Berkeley, USA), keynote and invited presentations, the program provided insights into the latest trends and strategies actionable to deal with the practical challenges faced by the community.
