The Institute of Optical and Electronic Materials is looking for a Research Scientist (f/m) with specialisation in photonic crystals, quasicrystals and disordered media.
The project “Quasi-disordered structures with 2D and 3D complete photonic bandgaps with arbitrarily small refractive index contrast” will be financed from a DFG (German Research Foundation) grant in the frame of the priority programme “Tailored Disorder – A science- and engineering-based approach to materials design for advanced photonic applications” (SPP1839):
The research will be focused on the development of 2D and 3D quasicrystal structures with a complete photonic band gap at small refractive index contrast. The dielectric distribution of these quasicrystals is mathematically obtained by a superposition of sinusoidal gratings with defined orientation and random phase. The designed structures will be investigated theoretically and experimentally. Up to now a 2D quasicrystal was designed with complete TE and TM band gaps with refractive index contrast as small as 1.1. It is also envisaged to obtain complete photonic band gap in 3D quasicrystals with refractive index contrast of 1.6 and below. Similar structures were also considered for tailored scattering in our publication: L. Maiwald et al., Opt. Exp. 26, 11352 (2018), https://doi.org/10.1364/OE.26.011352
- Theoretical approximation to predict the complete band gap opening
- Design of 2D and 3D quasicrystals with complete photonic band gaps
- Simulation of the local density of states
- Determination of the polarisation effects on the band gap opening
- Experimental realisation of structures with 2D and 3D lithography
- Experimental confirmation of complete photonic band gap
Desired skills and experience
- M.Sc. or PhD in physics or electrical engineering with focus on integrated or theoretical optics
- Demonstration of experience in theoretical description and numerical modelling of structured optical media through publications in peer-reviewed journals and employment references
- Demonstration of experience with photonic crystals, quasicrystals and/or disordered media through publications in peer-reviewed journals and employment references
What we offer
Fixed term contract for 3 years with possibility for PhD.
The employment contract is based on contracts for the German civil service (13 TV-L).
We particularly welcome applications from women. Preference will be given to severely disabled applicants provided equal qualifications.
How to apply

The Institute of Optical and Electronic Materials at Hamburg University of Technology has its main research focus in silicon photonics, structured optical materials and thermal photonics. In the field of silicon photonics there is extensive experience with integrated structures for light manipulation on chip. The structured optical materials include metamaterial, opals, photonic glasses and nanoporous metals. The thermal photonics is studied in the frame of DFG Collaborative Research Center (SFB 986) “Tailor-Made Multi-Scale Material Systems – M³”, where the institute director is one of the coordinators. The institute has all necessary equipment to conduct described simulations and experiments.
