In the article a novel design method for silicon ring resonators is presented that yields a free spectral range robust to fabrication variations. The work provides an important extension of the generic design approach exploiting cancellation effects using two waveguides, which so far was limited to Mach-Zehnder interferometers.

Dr. Yang Song is an associate professor from the Department of Information Physics & Engineering, Nanjing University of Science & Technology, China.

The three-day festival Highlight Delft will take place halfway through February. The festival takes you along beautiful historical sites in Delft, laboratories on the TU Delft Campus and unique locations, some of which open their doors especially for Highlight Delft.

Hina Vuijk joined the lab of Daan Brinks for her Applied Physics MEP. She will use imaging spectroscopy to investigate the photophysics of voltage-sensing Archaerhodopsin proteins.

Take an old webcam, remove the infrared filter, and just like that you have your own ghostbusters- inspired ‘detector’. It sounds easy, but we all know there is science behind this simple night vision trick. Thim Zuidwijk (ImPhys) is bridging the gap between practice and theory in the field of optics.

In the High Tech Systems and Materials program 2019 the project NanoRheoOCT has been granted to Dr. Jeroen Kalkman. This project is a collaboration between University Utrecht and a commercial partner. The researchers in this proposal develop a novel type of optical sensor based on optical coherence tomography to quantify the motion and flow of very small particles (macromolecules and nanoparticles).

We would like to welcome our new MSc student Anish Mukherjee. He will work on the project: ‘Analysing Single-Molecule Emission Patterns using Deep Learning’. Sjoerd Stallinga, Bernd Rieger and Rasmus Thorsen will be his supervisors.

Nico de Jong (ImPhys) tells on the Dutch radiostation NPO Radio 1 about ultrasound and its broad variety of applications.

Why would you want to share your microscopy data? If microscopy data were more findable and accessible it could facilitate ground-breaking discoveries! Bernd Rieger (ImPhys) and Katy Wolstencroft (Leiden University) talked about this on the 10th of December and present their plans for creating a national infrastructure for advanced light microscopy in the life sciences.

A new super-resolution microscopy technique has been published with Nature Methods this week The work is a TNW/3mE collaboration between Jelmer Cnossen, Taylor Hinsdale, Rasmus Thorsen, Carlas Smith, Bernd Rieger, and Sjoerd Stallinga, with external partners in Utrecht and Munchen. The paper is called “'Localization microscopy at doubled precision with patterned illumination” and is about the use of fine periodic illumination patterns for a better resolution in single-molecule based super-resolution.
