Scientist in The Field of Fiber Preform Development

vor 5 Monaten


Ettlingen, Deutschland Fraunhofer-Gesellschaft Vollzeit

You are thrilled by both conceptual questions and experimental work in the laboratory as well as the optimization and further development of components for high-power fiber lasers and would you like to help advance the state of the art in fiber lasers? You are a team player, yet willing to meet some tough challenges on your own? You wish to obtain a doctor degree or are interested in post-doc studies? Moreover, you do not mind being involved in projects with defence-related background?

**What you will do**
- You will develop, investigate and optimize processes for the realization of fiber preforms using MCVD technology as well as gas-phase or solution-doping techniques for active fibers in the spectral range > 1.9 µm (thulium and holmium doping).
- You will realize, investigate and optimize fiber preforms for multi-clad fibers, polarization-maintaining fibers and photonic crystal / bandgap fibers.
- You will contribute to the scientific investigation of fiber lasers to evaluate different fiber laser architectures in a broad team of experts in the field of photonic components, laser sources and nonlinear converters.
- You will work independently on projects in the field of fiber preform research and write reports and publications in English, or if possible, German language.

**What you bring to the table**
- Degree (diploma/master) in physics, chemistry, electrical engineering or equivalent disciplines
- Knowledge in realization of fiber preforms (MCVD technology, solution doping, glass working) and related equipment (MCVD system, glass-working lathe, gas supply systems, HF etching, etc.)
- Knowledge and relevant professional experience in fiber drawing and basic knowledge in fiber lasers would be of advantage.

**What you can expect**
- Free space for personal scientific development and the opportunity to push forward issues and projects on your own initiative
- Excellent, state-of-the-art technical equipment with partially not commercially available equipment
- A motivated team ensuring mutual inspiration owing to the interdisciplinary composition
- A wide range of further training
- Family-friendly conditions (flexible working hours, home-office regulations in line with the requirements of the position, etc.)

The employment is on a fixed-term 2 year contract with the possibility of prolongation or transformation into an unlimited employment.

With its focus on developing key technologies that are vital for the future and enabling the commercial utilization of this work by business and industry, Fraunhofer plays a central role in the innovation process. As a pioneer and catalyst for groundbreaking developments and scientific excellence, Fraunhofer helps shape society now and in the future.
