We are the Photonic Quantum Systems (PQS) Department at Fraunhofer IOF , a diverse and international team of more than 40 members from different cultural and academic backgrounds. We foster a welcoming, collaborative, and stimulating working environment that encourages the open exchange of ideas, knowledge, and experiences. Our research focuses on advancing quantum optics, photonics, and optical technologies, combining fundamental theoretical understanding with experimental research and practical applications. We value curiosity, creativity, and teamwork, providing an environment where students and researchers can develop their scientific and technical skills while contributing to innovative research projects.
Topic: Spatial-Mode Demultiplexing (SPADE) for Super-Resolution Imaging
The goal of this project is to develop and characterize an experimental optical setup for spatial-mode demultiplexing (SPADE) using Hermite–Gaussian modes. The student will assist in designing, building, and aligning the optical system, as well as investigating its performance in resolving closely spaced incoherent optical sources. Key metrics such as mode separation efficiency, optical losses, and spatial resolution will be measured and optimized, with the aim of evaluating SPADE as a technique for super-resolution imaging in microscopy.
These are your responsibilities:
- Assist in the design, construction, and alignment of an experimental optical setup for spatial-mode demultiplexing (SPADE)
- Implement and optimize the generation and detection of Hermite–Gaussian spatial modes
- Characterize the optical system in terms of mode separation efficiency, optical losses, and alignment sensitivity
- Perform experiments to investigate the resolution of closely spaced incoherent optical sources
- Analyze experimental data and evaluate the performance of SPADE for super-resolution imaging applications in microscopy
