PhD scholarship in Numerical Modelling of Ultrafast Nonlinear Effects in Gas-Filled Hollow-Core Fibers

jobbeskrivelse:

The Fiber Sensors & Supercontinuum Group at DTU Fotonik, Department of Photonics Engineering at the Technical University of Denmark is seeking a highly motivated and talented PhD candidate in the field of ultrafast nonlinear optics using gas-filled hollow-core antiresonant fibers.

This Ph.D. project is enabstractJV_titled “Numerical modelling of ultrafast nonlinear effects in gas-filled hollow-core fibers” and it is part of the project “UVSUPER: Ultra-Violet supercontinuum sources and pulsed lasers for the semiconductor industry” funded by Innovation Fund of Denmark. The main goal of the current project is the demonstration of a stand-alone deep ultraviolet supecontinuum source covering the 200 nm – 1600 nm region using gas-filled hollow-core antiresonant fibers. The project is in collaboration with Denmark’s National Metrology Institute (DFM) and NKT Photonics A/S.

Responsibilities and tasks
The PhD fellow will be part of the project UVSUPER and his/her responsibility will be to numerically support the research activities of the project towards the development of a stand-alone deep ultraviolet supercontinuum source. In particular he/she should be responsible to: 

• Accurately model the guiding properties of a hollow-core fiber using the finite element method.
• Develop a unidirectional, full-field, spatio-temporal code for propagation simulations.
• The developed code should also include a full polarization model, intermodal coupling, dispersion, Kerr effect and self-focusing as well as ionization and plasma dynamics.

Qualifications
Candidates should have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

In particular, candidates are required to have: 

• a Master’s degree or a very good first degree in Physics, Engineering or Material Science
• track record within the areas of fiber modeling using COMSOL and Matlab
• Basic knowledge of fibre optics and waveguides, nonlinear optics and laser physics.

At the time of recruitment by the host organization, candidates must be in the first four years (full-time equivalent research experience) of their research careers, and have not been awarded a doctoral degree.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.    

Assessment
The assessment of the applicants will be made by Associate Professor Christos Markos and Professor Ole Bang.
