Happy New Year ! Account created for the group of Rachel Grange to tweet our posters #pom20 Photonics Online Meetup on Jan 9th !

Building blocks for nonlinear #photonics are realized using GaAs nanowires. Steering of the Second Harmonic beam with sliced NW and switching of the SH with flexible metamaterials out of NW are shown @ONG_ETH Photonics Online Meetup #POM20


On-chip optical resonators are realized in thin-film lithium-niobate on insulator for future applications in the linear and non-linear regime. First results on racetrack and Bragg resonators are presented. @ONG_ETH Photonics Online Meetup #photonics #POM20 #AcademicTwitter


Can #ElectroOptic modulators exist without high quality epitaxial growth of thin films? Here, we employ barium titanate nanoparticles to realize ElectroOptic active meta-coatings. @ONG_ETH Photonics Online Meetup #photonics #POM20 #AcademicTwitter #OpticalMaterials #metamaterials #ETH


@ONG_ETH we use lithium niobate thinfilms for metasurfaces. What about actively tuning them? We investigate the influence of Pockels effect on optical resonances in nanostructured lithium niobate. ETH Physics ETH Zurich Photonics Online Meetup #POM20Ju #POM20LM #photonics #AcademicTwitter


Can electro-optic nanomaterials outperform single crystals? Check out our work on nanoparticle-films based on BaTiO3 nanocrystals. Photonics Online Meetup,@ONG_ETH,Rachel Grange,ETH Physics,Maria Timofeeva,ETH Zurich #POM20ju #POM20LM #nanotechnology #optics #AcademicTwitter


Abstracts for Photonics Online Meetup are due in 2 weeks (Dec 1)! Don't miss this chance to present your research on #photonics! New this year: a free #virtual #job fair & #tutorials! #PhDlife #AcademicChatter Link: buff.ly/2IvRdWE


We actively tune the transmission of a metasurface using the electro-optic effect of Lithium Niobate. MHz speed modulation at low power consumption achieved. Discuss with us in the Gather.town session! #POM21Ja #POM21meta #photonics #AcademicTwitter Dr. Flavia Timpu


Exploring ICP etching parameters for an Ar plasma to achieve redeposition free etching of lithium niobate thin-film integrated circuits with the goal to push quality factors of resonators consistently into the millions. Rachel Grange nanofabPOM #nanofabPOM #AcademicTwitter



Another one from the LNOI Team! ๐ We demonstrate upconversion from the telecom to the visible in a high-speed electro-optical modulator. Read more about how this technique can enhance the extinction ratio of amplitude modulators: arxiv.org/abs/2404.09787 ETH Zรผrich ETH Physics arXiv.org


In our newest arXiv.org paper we demonstrate entangled photon-pair generation in a plasmonic metasurface on an epsilon-near-zero material with a thickness of just 68 nanometers, one of the thinnest ever SPDC sources! ETH Physics Tsinghua University Wenhe Jia arxiv.org/abs/2405.03493
