Single Photon Detection for Data Communication and Quantum Systems

Many single photon detection systems are based on the technology of superconducting nanowires. But despite their high detection efficiency, the need of cooling them to cryogenic temperatures prohibits their widespread usage. This book shows the progress of integrated (thick) CMOS SPADs towards high photon detection probabilities and applications such as in low-cost consumer data communication and high-end single-photon counting for quantum applications. Newest research results are introduced and comprehensively detailed. Key Features The topic is covered from basics to applications. The properties of discrete SPADs and of integrated SPADs are compared in compact form. Dedicated circuits to exploit discrete and integrated SPADs are introduced and explained in detail. Microelectronics and optoelectronics are combined in an easily understandable way. Numerous elaborate illustrations and tables facilitate and enhance comprehension.
