Picocavities: confining light below the size of an atom

Jeremy Baumberg, University of Cambridge (UK)

We show how plasmonically-enhanced light-induced van-der-Waals forces pull single adatoms from metal facets, to create picocavities which confine light to volumes <1nm3. The thousand-fold stronger optical forces depend on nearby molecules as well as temperature and local optical field, and offer a route to single molecule optical tweezers.


Bose-Einstein Condensation, Lasing and Topological Photonics with Plasmonic Lattices

Päivi Törmä, Aalto University (Finland)

Arrays of metal nanoparticles host collective plasmonic-optical modes. We have observed lasing and Bose- Einstein condensation when such plasmonic lattices are combined with organic molecules, showing unique sub-picosecond dynamics, coherence properties and polarization textures. Recently, we have observed lasing in bound-state-in-continuum modes with a topological charge. We have also shown that magnetic field opens a gap between degenerate modes and can be used for on-off switching of lasing, which opens new prospects for studies of topological photonics.


Metasurface Laser Lightsails

Harry Atwater, California Institute of Technology (USA)

Nanophotonic design principles can enable self-stabilizing optical manipulation, levitation and propulsion of ultralight macroscopic-sized (i.e., mm, cm, or even meter-scale) metasurface "lightsails"via radiation pressure from a high power density pump laser source. Here we examine stringent criteria for the lightsail metasurface design, and dynamical and opto-mechanical stability, and thermal management. We discuss the dynamical stability analysis, as well as first experimental steps in characterization of small (<1 mm) microscale lightsails.


Device technology and vision for a better life empowered by meta-photonics

Duheon Song, Samsung Advanced Institute of Technology (Korea)

In this talk, I will present noticeable advances in the device technology for information and vision applications based on meta-photonics. The development in the field of integrated electronics devices has been incredibly fast, and this rapid development has been driven and accelerated by pioneering semiconductor manufacturing technologies that allow extreme scale-downs and creation of 3 dimensional structures. Meta-photonics can provide innovative platforms to produce unprecedented synergetic effect with electronics due to its distinguished capability of manipulating the control of light at the deep subwavelength scale. I will address how device technologies based on meta-photonics can contribute to making a better life, and share remarkable achievements and future goals we are working on.



Nikolay Zheludev, University of Southampton (UK) & NTU (Singapore)

Optical imaging and metrology of nanostructures exhibiting Brownian motion is possible with resolution beyond thermal fluctuations and speed to resolve their dynamics. This opens the case for picophotonics (atomic scale photonics), the science of interactions of picometer-scale objects and events with light.
