Special Issue Information
Dear Colleagues,
In recent times, there has been a noticeable surge in research interest surrounding photodetectors designed to achieve single-photon sensitivity. This burgeoning interest is primarily motivated by the demands of imaging and sensing tasks with low photon budgets, such as LiDAR, deep tissue imaging, and quantum information applications. Two prominent examples of such detectors include single-photon avalanche diodes (SPADs) and superconducting nanowire single-photon detectors (SNSPDs). Research efforts related to these detectors span a wide spectrum, encompassing process development with emerging materials, strategic integration at the system level, and the development of algorithms for image reconstruction.
We extend a warm invitation for submissions to this Special Issue, entitled "Emerging Topics in Single-Photon Detectors", in the form of basic research, methodological investigations, and cutting-edge applied research. Both regular research papers and comprehensive review articles are welcome, addressing the following areas:
- Fundamental research delving into the physics and signal processing techniques that account for the quantum nature of single-photon detection;
- Modeling and fabrication techniques for single-photon detectors, with a focus on novel material systems and innovative device structure designs;
- Exploring advanced sensing modalities made possible by single-photon detectors and their diverse range of applications;
- Advancements in the development of multimodal, multispectral, and/or multiscale sensing systems leveraging single-photon detectors;
- Innovative data processing methodologies, including the application of advanced algorithms such as machine learning and deep learning;
- Validation studies showcasing the effectiveness of single-photon detection methods in the context of biomedical and clinical research.
Your contributions to this Special Issue will play a pivotal role in advancing our understanding and application of single-photon detectors across various domains of science and technology.

Abstract: The integration of Single Photon Avalanche Diodes (SPAD) in CMOS Fully Depleted Silicon On Insulator (FD-SOI) technology under the buried oxide (BOX) and the silicon film containing the transistors makes it possible to realize a 3D SPAD at the chip level. In our study, a nanostructurated layer carried out by an optimized arrangement of the Shallow Trench Isolation (STI) present above the photosensitive zone generates light trapping and consequently light sensitivity increase in front side illumination. A simulation methodology is presented coupling electrical and optical data in order to optimize the STI trenches (size and period) and to estimate the Photon Detection Probability (PDP) gain. Then a test chip was designed, manufactured and characterized demonstrating the PDP improvement thanks to the STI nanostructuring while maintaining a comparable level of Dark Count Rate (DCR).
