Doctoral position at Department of Electronics and Nanoengineering at Aalto University, in Espoo, Finland. DC12: Design, fabrication, and characterization of reconfigurable and time-varying optical metasurfaces

Main supervisor: Prof. Viktar Asadchy[AALTO]
Co-supervisors/mentors:  Prof. Rockstuhl [KIT] and Prof. Díaz-Rubio [UPV]

Objectives

• To design optical metasurfaces capable of complex reconfigurable functionalities while restricting control to a single, or otherwise limited, discrete set of tuning parameters, enabling practical global actuation and robust device operation.
• To design optical metasurfaces and material platforms exhibiting time-varying responses. Using adjoint-based optimization and spatial structuring, to realize complex time-modulated medium dynamics with realistic material constraints and experimentally feasible excitation and driving schemes.
• To fabricate and experimentally characterize the designed prototypes, and to validate their reconfigurable and time-varying performance through quantitative comparison with analytical modeling and full-wave simulation results.

This position is part of the MetaTune  Doctoral Network "Reconfigurability using inversely designed metasurfaces", which has been funded under the Horizon Europe Marie Skłodowska-Curie Actions (MSCA) program.

Acquire knowledge

During the thesis, the candidate will acquire a solid understanding of the theoretical and practical requirements for designing optical metasurfaces with complex reconfigurable and time-varying responses, with particular emphasis on achieving rich functionality under a single or otherwise limited set of discrete tuning parameters. In parallel, the candidate will gain in-depth knowledge of time-modulated photonic media, nonlinear optics, adjoint-based optimization strategies for high-dimensional inverse design, and realistic material and excitation constraints at optical frequencies. The candidate will also develop practical expertise in prototype fabrication, experimental characterization, and quantitative validation of measured performance against analytical models and full-wave simulations.
