At the Leibniz Institute of Photonics Technology (Leibniz IPHT) we are looking in the Research Department Nanooptics for a part-time (75%) position for a PhD candidate (m/f/d) The position is to be filled from 1 December 2025 and is initially limited to a period of 3 years. An extension will be sought if suitable. The Leibniz-IPHT is a university independent research institute with close connection to the Friedrich-Schiller-University Jena and member of the Leibniz association. Job description: The position is part of the subproject C1 of CRC-1375 NOA with the focus on exploring fundamental non-linear process of light matter interaction in low dimensional nanostructures. In subproject C1, a plasmonic hot spot-assisted time-resolved broadband coherent Raman spectroscopy method will be explored to study local chemical reactions at single-molecule level. Rationally designed nanostructures will be used to generate localized hotspots with the designed properties for the enhancement of the sensitivity of coherent anti-Stokes Raman spectroscopy (CARS). The target is to monitor local chemical reaction with temporal resolution and single-molecule level sensitivity. The selected person will perform simulations to design the structure (FDTD, COMSOL), nanofabrication to realize the structure (EBL, FIB), and optical characterization to investigate the optical responses of the nanostructures and the molecule-structure hybrids (in collaboration with other groups). Details of the research can be found at: https://www.noa.uni-jena.de/1254/areas. Your field of activity includes: Performing simulations, nanofabrication, optical measurements Organizing meetings with supervisors to give regular reports on the progress Presenting research results in conferences and publishing papers in reputed journals Supporting related research activities of the group Your qualification: Master’s degree or the equivalent in physics, chemistry, photonics, or related fields. Desired knowledge and skills: Hands-on experiences in one of the followings: Electromagnetic simulations (FDTD, COMSOL, etc.) Laser microscopy and spectroscopy Nanostructure fabrication (EBL, FIB, etc.) Having published papers in scientific journals is greatly desired Hands-on experiences in MATLAB, LabView, Python, etc. Hands-on experiences in 3D graphics creation software (Blender, SketchUp, 3ds Max, etc.) Good English communication skills Ability to work independently and to collaborate with interdisciplinary scientists We offer: An open welcoming culture and an inclusive and interdisciplinary working environment: Located on the Beutenberg campus in Jena, Leibniz-IPHT is home to more than 400 employees from around the world working at the interface of physics, biochemistry, technology, data science and medicine to develop the photonic technologies of tomorrow. World-class equipment and facilities : Leibniz-IPHT has a large number of physics, chemistry and biology laboratories at the highest level. It also has state-of-the-art fiber drawing and clean room facilities (including lithography facilities) as well as microfluidics fabrication and big data computing facilities. Thorough and comprehensive personal training : Transferring good practices in scientific working and outreach is one of our main focus points. In a respectful and appreciative environment, you will learn everything you need for a career inside and outside of science. Moreover, plenty of workshops and opportunities for scientific exchange are offered by the Leibniz IPHT, as well as the Abbe School of Photonics and the Graduate Academy of the Friedrich-Schiller University Jena. A family-friendly working environment with support offers for the compatibility of family and work (e.g. parent-child office, campus kindergarten places, advice on family care situations from trained care guides and much more). Flexible working time models as well as 30 days vacation/year, special annual payment and bridge days. Jena - City of Science : a young city with a vibrant local cultural agenda! Salary: Salary is in accordance with the regulations of the TV-L and your qualifications and experience. About us: We are a modern, internationally focused research institute.
