Tuwhiri at the EGU General Assembly in Vienna
Florian Sedlmeir and Hannah Kessenich presented the programme's photonics and atmospheric science work to around 20,000 geoscientists.

Expert — Resonator Physics
University of Otago
Florian Sedlmeir is a Research Fellow and Marie Skłodowska-Curie Fellow at the University of Otago. His research focuses on high-Q whispering-gallery-mode resonators, nonlinear optics, and the conversion of microwave and terahertz signals to the optical domain. He completed his PhD at Friedrich-Alexander University Erlangen-Nürnberg, carrying out his research at the Max Planck Institute for the Science of Light, and subsequently worked in both academic research and industry before returning to the University of Otago in 2022. His current work explores electro-optic frequency conversion for low-noise millimetre-wave and terahertz detection, as well as microwave-to-optical interfaces for quantum technologies.
Millimeter-Wave Atmospheric Radiometry via Nonlinear Optical Upconversion
The monitoring of the Earth’s atmospheric composition requires very sensitive satellite-based measurements that detect the thermal radiation emitted in the millimeter-wave and …
Visualization and selective manipulation of sub-terahertz whispering gallery modes
The development of technologies based on electromagnetic resonant structures usually relies on precise understanding of the spatial form of the supported modes. In millimeter-sized …

Multichannel upconversion of terahertz radiation in an optical disk resonator
Second-order nonlinear optical processes allow the conversion of electromagnetic signals to a higher frequency domain. Such so-called "upconversion" processes have been of interest …
