DEVELOPMENT OF ULTRA-FAST ELECTRONICS FOR TIME CORRELATED SINGLE PHOTON COUNTING APPLICATIONS
Time-Correlated Single Photon Counting (TCSPC) is a cornerstone technique in time-resolved optical measurements, enabling the detection of ultra-weak signals with sub-picosecond resolution. This thesis presents the development of ultra-fast, scalable, and versatile front-end electronics optimized for TCSPC systems. The proposed architecture addresses critical performance bottlenecks such as timing jitter, dead time, and detection throughput. Special emphasis is placed on supporting next-generation techniques, such as Pro-active TCSPC, which demand exceptionally fast and accurate electronics to overcome pile-up limitations and operate at high photon count rates. The designed electronics are compatible with both custom and commercial single-photon detector technologies and have been rigorously validated through simulation and experimental testing. The resulting system not only minimizes dead time and enhances timing precision but also supports high-density, multi-channel configurations.
