SUMMARY:Nonlinear wave-mixing as a route to transparent AR displays
DESCRIPTION:Title: Nonlinear wave-mixing as a route to transparent AR displays \nLocation: GB220 \nTime: 3-4 pm\, July 31st\, 2026 \nAbstract: \nNonlinear wave-mixing opens an entirely new pathway for Augmented Reality displays. Unlike conventional approaches\, this method harnesses nonlinear optics to produce displays that remain fully transparent while simultaneously generating daylight-bright images suitable for near-eye viewing. \nWe present recent advances in this technology\, including the creation of a pupil-replicated eye-box and a field of view exceeding 30 degrees. Importantly\, we also demonstrate how a single display can generate red\, green\, and blue virtual images—an essential step toward a fully immersive full-color experience. \nOur approach is fundamentally original: the entire optical wavefront is generated through wave-mixing of beams structured by standard spatial intensity modulators. We detail implementations using both LCOS and DMD platforms\, underscoring the versatility and broad potential of this method. \nBio: \nProf Peter GR Smith has worked at the Optoelectronics Research Centre at the University of Southampton. He is Professor of Electronics and Computer Science\, and works on optics\, lasers\, photonics\, quantum technologies and display technology. He is a Fellow of Optica\, the IET\, the IoP and the GFCC. Prof Smith is the founder of three companies\, Stratophase\, Covesion and Smith Optical. \nIn University Leadership he has served in roles including Associate Dean\, CEO of University of Southampton Malaysia\, and as Associate Vice-President and Pro-Vice Chancellor International Projects. He has been a Member of both the University Senate and Council. In his International Role he has led Southampton’s engagement with a number of University Networks\, including World-Wide Universities Network\, RENKEI (where he was UK Co-Chair) and is a fellow of GFCC\, IET\, IOP and Optica. \nPeter is leading a new spin-out company from Southampton\, Smith Displays\, commercialising a radically new approach to augmented reality displays. The new technology solves the challenges with existing AR tech – offering daylight brightness\, total transparency and a solution to the nausea issues that have hampered adoption of AR/XR/VR display technology. \n
