Postdoc in experimental semiconductor nanophotonics DTU Electro

The Department of Electrical and Photonics Engineering at the Technical University of Denmark (DTU) invites applications for a postdoctoral position in Experimental Semiconductor Nanophotonics.

We are seeking a highly motivated and skilled researcher to investigate a new class of semiconductor nanocavities developed by our team. Based on extreme dielectric confinement (EDC) these structures confine light far below the wavelength scale. The project will explore their fundamental physics and their potential for new nanophotonic particular new types of nanolasers.

The research is funded by Villum Fonden and conducted in close collaboration with NanoPhoton Center for Nanophotonics a Center of Excellence investigating enhanced lightmatter interactions in nanocavities. You will join a large team of researchers exploring various aspects of EDC cavities.

The position is primarily experimental with a strong focus on short-pulse pumpprobe spectroscopy and advanced optical characterization of nanophotonic devices. You will also have opportunities to develop new device concepts and contribute to fabrication in DTUs state-of-the-art cleanroom facilities.

The position offers the opportunity to conduct high-impact research with potential applications in quantum technologies and integrated photonics. You will join a dynamic collaborative environment with access to cutting-edge optical laboratories and cleanroom infrastructure.

Qualifications

• A PhD in physics photonics or a related field.
• Strong background in experimental optics or nanophotonics.
• Experience with ultrafast optics pump-probe spectroscopy or semiconductor nanostructures is a strong advantage.
• Familiarity with nanofabrication processes is desirable but not required.

As a formal qualification you must hold a PhD degree (or equivalent).
