SPIE Photonics Europe
Strasbourg, France
April 12-16, 2026
SPIE Photonics Europe will take place from April 12-16, 2026, at the Palais de la Musique et des Congrès in Strasbourg, France. At this leading trade fair and conference for photonics, laser technology, and optics, top-class researchers will meet industrial users, e.g., in quantum technology and sensor technology. Laser Components will participate in the Quantum Technologies Conference 2026 with a scientific presentation on »Single-Photon Counting Modules«. At the accompanying exhibition, our experts from Laser Components France will also be available to answer all your questions about our comprehensive portfolio of detectors and emitters.
We are looking forward to your visit!

Topic: Characterization of a Single Photon Counting Module
with High Photon Detection Efficiency
and Low Dark Count Rate

Abstract
This paper provides a detailed overview of the structure and functionalities of a Single Photon Avalanche Detector (SPAD) with Very Low K (VloK) and a Single Photon Counting Module (SPCM) with a fast Active Quenching Circuit (AQC). It further discusses the impact of temperature and overvoltage on the intrinsic parameters of the SPAD. The novel AQC performance opens a wide range of possibilities for SPCM functionality, such as dead time or timing jitter. The effects on other SPCM parameters are examined and discussed.
