If you aim at scientific excellence and want to establish a career as a scientist within fiber lasers and supercontinum sources and their high-level applications within imaging and spectroscopy, then we have the ideal opportunity for you. Come and be a part of the “Table-Top Synchrotron” project and one of the world’s strongest groups in this field in our quest to develop supercontinuum sources that outcompete synchrotrons from the deep ultraviolet (deep-UV) down to 33 nm to the mid-infrared (mid-IR) up to 15 µm.
To cover this enormous bandwidth we are developing 4 new all-fiber supercontinuum sources, or beamlines. The UV beamline 1 is based on gas-filled hollow-core silica fibers and meta-surfaces and will cover 33-1100 nm, extending the record 113 nm UV edge to 33 nm. The near-IR beamline 2 is based on solid-core silica photonic crystal fibers covering 400-2400 nm and will use so-called all-normal dispersion (ANDi) fibers pumped with femtosecond lasers to achieve record low noise for spectroscopy and Optical Coherence Tomography (OCT) imaging applications. The same technology will be used for the low-noise beamline 3 covering 1-5 µm using commercial fluoride fiber. Beamline 4 will push the record IR edge in all-fiber mid-IR supercontinuum sources to 15 µm by using chalcogenide soft-glass fibers, in particular in-house fabricated sulfide, selenide, and telluride fibers.
Responsibilities and qualifications
This PhD study will focus on the development of the UV beamline 1, i.e., using gas-filled hollow-core fibers pumped with ultra-short femtosecond lasers to generate a supercontinuum reaching down into the UV, ultimately to 33 nm. In particular you will also develop different types of meta-surfaces in the clean room at DTU and develop a technique to attach these meta-surfaces to the end-facet of the fiber.
We therefore require you to have experimental qualifications within fiber optics and lasers, preferably also with modelling and/or fabrication of meta-surfaces and to document a drive to build things yourself.
You must 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.
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 DTU’s rules for the PhD education.
Assessment
The assessment of the applicant will be made by Professor Ole Bang, Professor Andrei Laurynenka, and by the DTU PhD Council.
