Our group has collaborated with Dr. Mariia Sidorova and the Integrated Quantum Optics Group on a new publication in the journal "APL Photonics". The paper by Dr. Mariia Sidorova and Timon Schapeler analyzes the physics of multi-photon absorption in superconducting nanowire single-photon detectors (SNSPDs) and provides a physical model for photon-number dependent jitter mechanisms in the detection process. These findings are important, e.g., for photon-number-resolving detector design and low-jitter applications, such as light detection and ranging (LIDAR).
The open access publication can be found here.
