We are looking for 3 PhD students who carry out technological and fundamental research on hybrid integrated semiconductor lasers and nonlinear optical conversion using integrated photonic circuits. The PhD students will work towards three directions:
- Hybrid integrated, single-frequency semiconductor lasers to reach the blue spectral range, providing tunability and record-narrow linewidth
- Hybrid integrated mode-locked semiconductor lasers that provide frequency combs with ultra-low jitter
- Supercontinuum generation and micro-resonator Kerr frequency combs for novel approaches in dual-comb imaging
The projects will extend our internationally leading position in the fields of chip-sized diode lasers with record- narrow Townes-Schawlow linewidth (DOI 10.1364/OE.398906), the realization of hybrid-integrated diode laser in the visible (DOI 10.1117/12.2565028), and of chip-based comb generation with record wide spectral coverage (DOI 10.1364/OE.23.019596). The research projects comprise all aspects from basic physics, e.g., modeling of laser dynamics and nonlinear conversion, design engineering of photonic integrated circuits and opto-electronic control, and proof-of concept demonstrations. The projects are carried out in collaboration with industrial partners that perform the fabrication, integration and packaging of photonic circuits and devices, and that are interested in applications.
About the group
We are an international team with diverse backgrounds reaching from theory, experimental physics, to optical and electrical engineering. We enjoy working with integrated photonics using methods from laser physics, nonlinear optics, photon-phonon-interaction and microwave photonics. Our goal is to provide leading progress in physics and technology of photonic light sources that are relevant for emerging applications, such as in optical communications and processing, precision metrology or optical sensing. We are part of a group of some 80 people that explore, within the research cluster Applied Nanophotonics (ANP), multiple aspects of modern photonics. These include integrated quantum optics, control of light scattering, XUV optics, laser processing, biomedical imaging, photonic crystals, photonic materials and sensing.

For detailed questions, please contact Prof. Klaus Boller
We are looking for candidates with a MSc degree in physics, physics engineering or photonics engineering, with a good background in lasers and modelling (e.g. VPI), in nonlinear optical conversion and spectroscopy, or in waveguide design and simulation (e.g. Lumerical and Comsol). The candidates should have experimental experience with guided-wave optics, e.g., in aligning optical waveguides or with characterization of waveguide circuits.
Suitable candidates have proficient oral and written English language skills, and are well-capable of scientific communication, also towards non-expert partners. Female candidates are equally encouraged to apply as we strive for working in a well-balanced team.

The University of Twente. We stand for life sciences and technology. High tech and human touch. Education and research that matter. New technology which leads change, innovation and progress in society. The University of Twente is the only campus university of the Netherlands; divided over five faculties we provide more than fifty educational programmes. We have a strong focus on personal development and talented researchers are given scope for carrying out groundbreaking research.
We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status or disability status. Because of our diversity values we do particularly support women to apply.
Within the TNW Faculty (Faculty of Science & Technology) of the University of Twente some 700 staff members and 2000 students are involved in training and research on the interface of chemical technology, applied physics and biomedical technology. Fields of application include sustainable energy, process technology and materials science, nanotechnology and technical medicine. Research, which enjoys a high profile both at home and internationally, has been accommodated in the multidisciplinary research institutes: Mesa+ Institute, TechMed Centra and Digital Society Institute. The faculty works together intensively with industrial partners and researchers in the Netherlands and abroad and conducts extensive research for external commissioning parties and funders.
