PhD scholarships on Theory, Fabrication, and Optical Characterization of Subdiffraction Photonic Nanocavities – Technical University of Denmark (DTU)

A recent discovery has shown that it is possible to confine light at length scales much below the diffraction limit in semiconductors. Previously, this was only considered possible in metals through the excitation of plasmons, which unfortunately are associated with large optical losses. This new discovery opens tremendous possibilities for realizing a new regime of strong light-matter interaction, with important applications in quantum technologies as well as for integrating photonics and electronics. Enabled by a newly funded ERC grant as well as a major grant from the Danish National Research Foundation, a number of Departments at the Technical University of Denmark are joining forces in the Center for Nanophotonics (NanoPhoton) to explore this new research field of extreme dielectric confinement.

We are now looking for up to three PhD students, who have excelled in their studies, to join our team, working towards new and highly ambitious research goals at the forefront of this new field. Our research addresses multiple areas and spans quantum optics, solid-state physics, nanotechnology, mathematical modelling, inverse design, integrated photonics, semiconductors, nanofabrication, and spectroscopy. See, e.g., https://arxiv.org/abs/2108.01681 and https://arxiv.org/abs/2111.06305 for our latest experimental breakthroughs, theoretical insights, and scientific background for the present positions. We aim to combine fundamental theory, device design, and our unrivalled capabilities in high-resolution silicon nanotechnology towards entering so far uncharted experimental regimes. The currently available projects include:

    • Quantum nonlinearities.
    • Optomechanical and Casimir interactions.
    • Light emission from hot electrons.

The successful candidates will interact with a dedicated team of highly motivated researchers, where we emphasize strong interaction between experiment and theory, independent thinking, and team spirit.

Responsibilities and tasks
The details, responsibilities, and tasks of the PhD projects will be tailored to the qualifications and interests of the applicants but will revolve around the headlines above. Most importantly, we seek highly motivated and excellent students with an interest in teamwork at the highest international level.

Qualifications
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. Our research relies heavily on theory/numerical design, nanofabrication, and optical experiments and we expect the successful applicants to master at least one of these aspects but we welcome applications from students who have demonstrated excellent academic performance in adjacent fields.

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
Candidates will be assessed by a panel consisting of Associate Professor Søren Stobbe and Professor Jesper Mørk.

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice.

NanoPhoton
The research vision of NanoPhoton – Center for Nanophotonics – is to explore the hitherto inaccessible regime of extreme dielectric confinement of light in optical cavities and to apply the associated enhanced light-matter interaction to solve fundamental outstanding challenges in chip-scale quantum and information technologies. To this end, we will develop the science and technology for a new class of optical nanostructures by combining fundamental electromagnetic and quantum optical theory with state-of-the-art nanofabrication and advanced experiments.

The Nanophotonics Section at DTU Fotonik
DTU Fotonik has 210 employees and is one of the largest research centers in the world focusing entirely on photonics. Research is performed within nanophotonics, photonic nanotechnology, lasers, quantum photonics, optical sensors, LEDs, photovoltaics, ultra-high speed optical transmission systems, and bio-photonics. The Nanophotonics section combines expertise in the synthesis and handling of nanomaterials, the fabrication of nanoscale devices, and theoreticians employing a wide palette of analytical and numerical techniques to provide better understanding of and control over the fundamental properties of light-matter interactions and in this way realizing new nanophotonic devices for emerging information and quantum technology.

Technology for people
DTU develops technology for people. With our international elite research and study programmes, we are helping to create a better world and to solve the global challenges formulated in the UN’s 17 Sustainable Development Goals. Hans Christian Ørsted founded DTU in 1829 with a clear vision to develop and create value using science and engineering to benefit society. That vision lives on today. DTU has 12,900 students and 6,000 employees. We work in an international atmosphere and have an inclusive, evolving, and informal working environment. DTU has campuses in all parts of Denmark and in Greenland, and we collaborate with the best universities around the world.
