Postdoc in AlGaAs Nonlinear Nanophotonics for Terahertz Detection - DTU Electro

We are seeking a highly motivated postdoctoral researcher with strong competencies in nanophotonics, nonlinear optics, metasurfaces, and nanofabrication to develop a new generation of high-sensitivity terahertz (THz) detectors based on nonlinear frequency upconversion. You will join an interdisciplinary research team at DTU working at the interface of integrated photonics, THz science, and advanced imaging.

Your research will focus on designing, fabricating, and experimentally demonstrating AlGaAs metasurface-enhanced THz-to-near-infrared converters, with the ambition of increasing conversion efficiency by orders of magnitude and enabling coherent focal-plane-array THz imaging.

The position offers the opportunity to develop cutting-edge nonlinear nanophotonic devices, work extensively with DTU Nanolab facilities, collaborate with leading international research groups, and contribute to a new platform for high-speed, hyperspectral and super-resolution THz imaging.

Responsibilities and qualifications Your primary responsibility will be to develop high-efficiency AlGaAs-based THz-to-NIR detectors using four-wave mixing and metasurface field enhancement. You will investigate the combination of microscale metallic THz structures and dielectric AlGaAs metasurfaces to enhance both THz and optical fields and optimize their spatial overlap1 …
