Filip Hjort

Doctoral Student at Photonics

Filip Hjort received the M.Sc. degree in Applied Physics from Chalmers University of Technology in 2016. The same year he started working as a PhD student in the group of Prof. ├ůsa Haglund, where he is focusing on the development of III-nitride vertical-cavity surface-emitting lasers (VCSELs) emitting in the ultraviolet and blue spectral regimes.
