The Laboratory for Nano-Optics deeply regrets the tragic accident and the death of Dr. Dmitry Fedyanin. We express our sincere condolences to Dmitry's family and friends. Dmitry was a recipient of a Walter Benjamin Position of the DFG on “Pulsed electrically driven single-photon sources on diamond” and since July 2023 he has been a research associate in our group. We have been collaborating since almost a decade on the electroluminescence from color centers in diamond. We mourn the loss of a good friend and of a talented young scientist.
Group member Navid Soltani obtains the PhD in Physics. Congratulations!
Our book chapter on ultrafast single-photon detection published in Advances in Nonlinear Photonics.
Group member Philipp Rauschel receives the Applied Photonics Award for his master thesis. Congratulations Philipp!
Our latest work on ODMR published in Adv. Quantum Technol.
