PhD scholarships in Nanolaser Physics and Integrated Photonics

Job type: 


Application deadline: 

Friday, January 31, 2020

We have open PhD projects within an evolving area of nanophotonics, funded by an ERC Advanced Grant from the European Research Council. The overall goal of the project is to explore, experimentally as well as theoretically, new types of nanophotonic devices based on so-called Fano resonances. These devices have rich and interesting physics, largely unexplored, with the potential to drastically reduce the quantum noise of nanolasers and increase their speed. These properties are important for future integrated photonic circuits with ultra-low energy consumption as well as for applications within quantum technology.

The ERC project targets the development of new theory for Fano lasers, fabrication of devices in DTU’s state-of-the-art cleanroom, as well as experimental characterization in DTU Fotonik’s advanced optical laboratories. We have recently made the first proof-of-principle demonstration of semiconductor Fano lasers based on semiconductor quantum dots in photonic crystals, and now we wish to pursue new ideas and applications.

With the present call, we wish to strengthen our theoretical activities on nanolaser physics, as well as the fabrication and experimental characterization of the lasers and related devices. The successful candidates will join a dedicated team of highly motivated researchers, where we emphasize strong interaction between experiment and theory, independent thinking and team spirit.

Responsibilities and tasks
One PhD project will primarily focus on theory, while the other project focuses on nanofabrication and experimental characterisation:

  • Project A keywords: Quantum theory of nanolasers; modelling of ultrafast dynamics and modulation; quantum noise properties; quantum dots and photonic crystals.
  • Project B keywords: Fabrication of nanolasers; e-beam lithography; experimental characterization of fundamental laser properties, including noise and dynamics.

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. Candidates with a strong background within optics and photonics, nanofabrication, laser physics, or applied mathematical physics are preferred. In the application please indicate which of the two projects above you are interested in.

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. You may read more about being a PhD student at DTU here.

Denmark’s capital, Copenhagen, is located some 10 km from DTU’s campus, offering a large variety of cultural possibilities.

Candidates will be assessed by Professor Jesper Mørk.
