Offer Description
The Institute of Photonic Systems and Technologies, the Hannover Centre for Optical Technologies (HOT), and the Cluster of Excellence PhoenixD welcome applications for the following position to be filled at the earliest possible date: Postdoctoral Researcher in Computational Electrodynamics and Inverse Design of Time-varying Metamaterials (ERC project TEMPORE) (salary scale 13 TV-L “FwN”, 100 %)
The position is initially limited to 3 years, with the possibility of extension.
About the project
This position is funded by the European Research Council (ERC) under the Horizon Europe programme (ERC Consolidator Grant TEMPORE). This project pioneers the inverse design of time-varying metamaterials operating on picosecond to femtosecond timescales. You will contribute to redefining how light can be controlled in space and time for fully reprogrammable, multifunctional nanophotonic systems.
Your role
The postdoctoral researcher will play a key role in the design, architecture, and long-term development of the computational platform underlying the ERC TEMPORE project, working closely with and under the scientific direction of Prof. Antonio Calà Lesina. Responsibilities include the following tasks.
Algorithm Development:
- Coordinate and actively contribute to the development of time-domain inverse design frameworks with time as a fundamental design parameter (4D design in space and time).
- Design and oversee scalable, memory-efficient, high-performance implementations targeting distributed-memory (MPI) and accelerator-based (GPU) architectures, including scalability studies, performance profiling, and optimization of large-scale 3D and 4D simulations.
- Define and implement the software architecture of a modular, scalable, open-source inverse design framework, including parallelization strategy, memory layout, performance optimization, and long-term maintainability.
- Implement and extend large-scale computational electrodynamics solvers (FDTD and related methods) for dynamic and nonlinear materials.
- Model advanced materials such as transparent conductive oxides, nonlinear media, and other ultrafast tunable materials.
- Application of these methods to simulate and design physically realizable 3D nanophotonic systems, such as dynamically tunable optical metasurfaces and metamaterials.
Collaboration & Dissemination:
- Lead methodological subprojects in close coordination with the PI.
- Coordinate and co-supervise doctoral researchers contributing to the shared computational framework.
- Possibility of working closely with experimental partners
- Publish high-impact research, present at international conferences, and enhance the scientific visibility of the group.
