From May 10th till May 14th was the digital CLEO conference USA 2021. The MQO group contributed with a talk from Timon Schapeler. His presentation can be found under the following link.
In our paper we demonstrate and verify quantum detector tomography of a superconducting nanowire single-photon detector (SNSPD) in a multiplexing scheme which permits measurement of up to 71 000 photons per input pulse.
We congratulate Nina Amelie Lange who has successfully completed her master's studies titled "Towards Cryogenic Parametric Down-Conversion in Lithium Niobate Waveguides".
We congratulate Dominik Kostiuk who has successfully defended his bachelor thesis titled "Monitoring the Refractive Indices of Lithium Niobate Waveguides under Cryogenic Conditions".
Timon Schapeler has a new publication titled "Quantum detector tomography of a 2×2 multi-pixel array of superconducting nanowire single photon detectors".
Congratulations to Moritz who now starts his PhD in the group of Camille Brès at EPFL. It’s been great to have you in the group and we wish you all the best in Lausanne.
From May 11th till May 15th was the digital CLEO conference USA 2020. The MQO group contributed with talks from three different people: Moritz Bartnick, Jan Philipp Höpker, and Frederik Thiele.
We congratulate Frederik Thiele, Moritz Bartnick and Felix Dreher (from left to right with Jun.-Prof. Tim Bartley) for successfully completing their bachelor's and master's studies. Frederik Thiele defended his master's project titled "Polarisation Converter in Lithium Niobate Waveguides at Cryogenic Temperatures". Moritz Batnick obtained his master's degree with his thesis about "Nonlinear Optics at Cryogenic Temperatures". Felix Dreher achieved…
From 21st-25th October Jan Philipp Höpker and Tim Bartley joined the Single Photon Workshop in Milan. Jan Philipp presented his work on “Characterizing integrated single photon detectors on lithium niobate waveguides”.
We visited the first fall meeting of the DPG in Freiburg. Frederik Thiele gave a talk on his results on a polarisation converter in lithium niobate at cryogenic temperatures. In a poster session Julian Brockmeier, Nina Lange, Maximilian Protte and Timon Schapeler presented their work on pump suppression for nonlinear processes, a SPDC source for cryogenic temperatures based on periodically poled lithium niobate, a hybrid platform based on silicon…
Frederik Thiele, Jan Philipp Höpker, and Moritz Bartnick presented their work on “Towards Cryogenic Polarisation Modulation in Lithium Niobate Waveguides”, “Integrated transition edge sensors on lithium niobate waveguides”, and “Towards an integrated PDC source at cryogenic temperatures” at the DPG-Frühjahrstagung in Rostock.
