3 positions for PhD students in integrated optics

Starting date: winter/spring 2020/2021, depending on circumstances
Application deadline: open until positions are filled

Job description

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 , hybrid-integrated diode laser in the visible, and of chip-based comb generation with record wide spectral coverage. 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.

Your profile

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.

Our offer

  • We offer you a four-year full-time position with a probational period of one year.
  • We provide excellent mentorship in a modern and a vivid research environment, with state-of-the art research facilities.
  • You benefit from a professional and personal development program.

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.
