Joining fellow fourth year CDT PGRs Henry Fernandez, Charlie-Ray Mann and Tom Collier at Nanometa 2019, Carlota Ruiz De Galarreta presented a poster- “All-dielectric hybrid silicon/Ge2Sb2Te5 optical metasurfaces for tunable and switchable light control in the near infrared” (abstract below).
NANOMETA 2019 aims to bring together the international Nanotechnology, Photonics and Materials research communities where most recent and challenging results and plans are discussed in the informal setting on a glorious mountaineering resort. The technical programme included invited and selected contributed papers in the areas of:
• Plasmonics, Metamaterials and Metadevices
• Quantum and Topological Nanophotonics
• New Materials for Nanophotonics
• Optical Super-resolution
Abstract:
All-dielectric hybrid silicon/Ge2Sb2Te5 optical metasurfaces for tunable and switchable light control in the near infrared
We report a novel reconfigurable metasurface based on the combination of all-dielectric arrays of silicon meta-atoms, with deep subwavelength (< 0/100) Ge2Sb2Te5 layers. Our approach allows to selectively and individually control electric and magnetic resonances.
