Óskar B. Helgason
Óskar Bjarki Helgason is a PhD student at the Department of Microtechnology and Nanoscience, Photonics Laboratory of the Chalmers University of Technology in Sweden. His research is focused on the dynamics and design of microresonator frequency combs.
Microcomb for Planet Hunters - A microcomb is a photonic device capable of generating a myriad of optical frequencies – colours – on a tiny cavity known as microresonator. Óskar Bjarki Helgason of the Chalmers University of Technology, Sweden, presents a game changing microcomb that could bring advanced applications closer to reality. For instance, this device could be used for the calibration of spectrographs used in astronomical observatories devoted to the discovery of Earth-like exoplanets.
