  • Front-End Readout Circuit Design for DEPFET Pixel Detectors in 65-nm CMOS 

    Gogolou, Vasiliki; Krüger, Hans; Dingfelder, Jochen (2026-05-06)
    This work presents a differential readout integrated circuit for DEPFET pixel matrices, with a systematic evaluation of trade-offs among key performance metrics such as power consumption, noise, and silicon area. Each ...

  • Strong coupling between WS2 monolayer excitons and a hybrid plasmon polariton at room temperature 

    Zhang, Yuhao; Schill, Hans-Joachim; Irsen, Stephan; Linden, Stefan (2024-04-15)
    Light–matter interactions between plasmonic and excitonic modes have attracted considerable interest in recent years. A major challenge in achieving strong coupling is the identification of suitable metallic nanostructures ...

  • Spectroscopic Gas Sensor Based on a Fiber Fabry-Perot Cavity 

    Saavedra, Carlos; Pandey, Deepak; Alt, Wolfgang; Meschede, Dieter; Pfeifer, Hannes (2022-10-17)
    Optical spectroscopic sensors are powerful tools for analyzing gas mixtures in industrial and scientific applications. Whilst highly sensitive spectrometers tend to have a large footprint, miniaturized optical devices ...

  • Fluctuation-Dissipation Relation for a Bose-Einstein Condensate of Photons 

    Öztürk, Fahri Emre; Vewinger, Frank; Weitz, Martin; Schmitt, Julian (2023-01-20)
    For equilibrium systems, the magnitude of thermal fluctuations is closely linked to the dissipative response to external perturbations. This fluctuation-dissipation relation has been described for material particles in a ...
