In this talk I will summarize our work towards novel laser-based display architectures for AR glasses within Meta Reality Labs Research. While near-term AR glasses products with displays are likely to be based on LCoS and uLED panels, in the long run the properties of lasers, incl. their high directionality, spectral purity, very high brightness and full polarization can enable superior display performance. I will focus on our recent progress on laser-scanning, laser-illuminated and photonic-integrated circuit based projector architectures, their key advantages and challenges when used in near-to-eye displays.
Daniel Greif, Ph.D physics, is a technical lead for laser-based displays in the display systems research group at Meta Reality Labs. His research focuses on developing novel display technologies for AR glasses and spans from developing Lissajous-scanning laser displays and laser-illuminated panel systems to photonic-integrated circuit based approaches. He received his PhD in physics from ETH Zurich (Switzerland) in 2013 in the field of experimental quantum optics, where he studied quantum simulation of graphene and quantum magnetism with ultracold fermionic gases in optical superlattices. During his time as a postdoctoral research at ETH Zurich and Harvard University from 2013-2018 he investigated topological phases of matter, resulting in the first experimental realization of the Haldane model, and used a high-resolution optical microscope with single-atom resolution to study various strongly correlated quantum phases. Prior to joining Meta he received an ERC Starting Grant for starting his own research group at the University of Heidelberg aimed at using ultracold atoms in optical tweezers to explore strongly correlated states and quantum computing.
