Professor Satoshi Iwamoto, Specially Appointed Professor Yasuhiko Arakawa, Visiting Associate Professor Yasutomo Ota (Associate Professor at Keio University) and their colleagues have successfully developed a compact optical device for integration that generates optical Skillmion beams, the next-generation topological light beam. Optical skyrmion beams are expected to be the light source of the next generation, as they enable optical communications with extremely high tolerance to external disturbances, etc. Until now, the device required the size of a desktop, but the research team has realized it as an optical element for integration for the first time using silicon photonics, utilizing strong optical confinement by a thin-wire waveguide, etc. This has paved the way for the development of the diverse possibilities of the next generation of optical skillmion beams at the level of optical integrated circuits, including not only next-generation optical communications but also new discoveries in optical measurement and interactions between light and matter. The resulting paper was published in OPTICA 14 November, a journal in the field of optics and photonics.
