Space-time Metasurfaces: Spatiotemporal Light Structuring with Dielectric Meta Optics

Dielectric meta-optics provide a compact platform for spatiotemporal light shaping through angular-dispersion engineering. The talk reviews a few use cases, such space–time optical merons realized by large-area birefringent metasurfaces and spatiotemporal spectral mappings that program polarization textures momentum–energy surfaces; Montgomery self-imaging effects via polarization-insensitive dielectric metasurfaces.

Murat Yessenov is a postdoctoral fellow at Harvard John A. Paulson School of Engineering and Applied Sciences under the supervision of Federico Capasso. His research focuses on investigating meta-optics capable of spatiotemporal shaping optical fields. Based on the previous efforts on dispersion-engineering of achromatic meta-lens and inverse-designed metasurfaces, Murat is interested in joint manipulation of light in spatial and temporal domains with application in structured light manipulation, nonlinear phase matching and optical atom trapping. Previously, his research focused on rotated chirped volume Bragg gratings for spectral analysis and pulse shaping in a compact form factor. Murat earned his Ph. D. at the College of Optics and Photonics (CREOL), University of Central Florida in Ayman Abouraddy’s group. During his Ph.D., he pioneered research on space-time wave packets—a novel class of spatiotemporally structured optical fields, where he developed the first free space optical setup to generate 3D space-time wave packets.

Murat’s Ph.D. work received multiple recognitions, including the Emil Wolf Outstanding Student Paper Award from OPTICA (2020), the Laser Technology, Engineering, and Applications Scholarship from SPIE (2022), the Boris P. Stoicheff Memorial Scholarship from OPTICA (2022), and the CREOL Student of the Year Award (2022). He has co-authored over 50 journal articles and 3 patents.
