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.

Experiments:
Surface Plasmon Resonance (SPR) Sensing
Conceived for Physics Bachelor, Master and Master in Nanoscience and Nanotechnology. In this laboratory experiment students become familiar with the concepts of surface plasmon resonance (SPR) and use the underlying principle to demonstrate the sensitivity of SPR to surface phenomena for sensing applications. Experimental and theoretical values of the physical quantity of the detected materials will be compared to find the experimental error and the sensitivity of the sensor.
SPR-Exp-Manual
Single Photon Sources (SPS)
Conceived for Physics Bachelor and Master. In this laboratory experiment students become familiar with micro-photoluminescence optical setups and the necessary optical devices for the detection and counting of single photons. Students will observe the quantum nature of light and understand the underlying principle behind photon counting and intensity fluctuations. Students will verify photon statistics for the demonstration of chaotic light, coherent light and single-photon sources.
SPS-Exp-Manual
Fluorescence Correlation Spectroscopy (FCS)
Conceived for Physics Bachelor and Master. In this laboratory experiment students become familiar with micro-photoluminescence optical setups and the necessary optical devices for the detection of molecular fluorescence in solutions. Students will use a technique called Fluorescence Correlation Spectroscopy (FCS) and they will learn how FCS can be related to the diffusion process and how to extract relevant information about the observed system.

Optically-Detected Magnetic Resonance (ODMR)
Conceived for Physics Bachelor and Master. In this laboratory experiment students become familiar with micro-photoluminescence optical setups, microwave sources and antennas, magnetic-field coils, and the necessary optical devices for the detection of magnetic resonance based on the nitrogen-vacancy color center in diamond. Students will use a technique called Optically-Detected Magnetic Resonance (ODMR) and they will learn how ODMR can be used to extract relevant information about the observed system (spin- and electronic-states configuration, magnetic-field strength and orientation).
