PhD candidate in the Research Department Fiber Photonics (f/m/d) in Jena

At the Leibniz Institute of Photonics Technology (Leibniz-IPHT) we are looking in the Research Department Fiber Photonics, Working Group Active Fiber Modules, from 1st January 2024 for a part-time (75%) position for a

PhD candidate (m/f/d)

The position is to be filled as soon as possible

and is initially limited to a period of 3 years.

Job description

The position to be filled involves participation in the Yellow research group. One of the goals of this group is the demonstration of novel Dy-doped fiber lasers in the so-called 'yellow gap'. One focus is the development of novel fused silica-based fiber lasers, where very different fiber core materials will be introduced to fundamentally extend the understanding of the interaction of Dy ions with different codopands and laser host compositions. In this way, perspectives for avoiding photoinduced effects and increasing laser efficiency ought to be revealed.

Your field of activity includes:

Investigation of the interaction of Dy ions with different codopands and laser host compositions
Investigation of laser-relevant properties of Dy-doped laser fibers (absorption and emission spectra, fluorescence lifetimes, excited-state absorption)
Investigation of Dy-doped laser fibers of different fabrication methods (MCVD method and Molten Core method)
Design and execution of fiber laser experiments on efficiency, power characteristics and other optical parameters
Design of suitable measurement setups for the investigation of fluorescence properties and excited-state absorption
Automation of the acquisition and processing of measurement data
Creation of simulations for the Dy-fiber lasers for the optimal design of the laser resonators
Collaboration in the investigation of photodarkening

Your qualification:

Master's degree in physics, photonics, materials science, or similar scientific discipline

Desired knowledge and skills:

Strong expertise in laser physics
Knowledge in fiber optics
Practical experience in working with optical fibers
Practical experience in fluorescence spectroscopy
Programming skills for data analysis (Python)

About us:

The Leibniz-IPHT is a university independent research institute with close connection to the Friedrich-Schiller-University Jena and member of the Leibniz association.

We are a modern, internationally focused research institute. Work-life balance is one of our central concerns. We value diversity and therefore welcome all applications - regardless of gender, disability, nationality or ethnic and social origin. If women are underrepresented in the area of the advertised position, they will be given preferential consideration in the hiring process if they are equally qualified.

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. We'll teach everything that is needed for a career inside and outside of academia in a respectful and enjoyable way. 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 rooms, 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!
