Special Issue Information

Dear Colleagues,

Single-photon detectors were invented approximately 90 years ago with the arrival of the photomultiplier tube. A single-photon detector with ultimate sensitivity is capable of registering photons, emerging with an indispensable role for extensive applications, including optical quantum information and communication, laser ranging, astrophysics, and high-energy physics. There are numerous material systems used for single-photon detection, generally: photomultipliers, semiconductors, and superconductors. The extension of single-photon detection to mid-infrared further facilitates the applications in astronomy, LIDAR, dark matter searches, and the fundamental study of fast molecular dynamics and chemistry. A set of performance tradeoffs or detector types among all material systems should be selected based on the needs of particular applications.

This Special Issue invites manuscripts that introduce the recent advances in “Single-Photon Detectors and Their Applications”, covering the wavelength from visible to mid-infrared. All theoretical, numerical, and experimental papers are accepted. Topics include, but are not limited to, the following:

  • Solid-state-based single-photon detector: physics, measurement, and applications;
  • Superconductor-based single-photon detector: physics, measurement, and applications;
  • Spatial multiplexing single-photon detector;
  • Hybrid detection system;
  • Mid-infrared single-photon detector;
  • Single-photon detection in existing and new categories of applications;
  • Photon number resolving.

Time-correlated single-photon counting (TCSPC) is a powerful technique for time-resolved measurement of fast and weak light signals used in a variety of scientific fields, including biology, medicine, and quantum cryptography. Unfortunately, given its repetitive nature, TCSPC is recognized as a relatively slow technique. In the last ten years, attempts have been made to speed it up by developing multichannel integrated architectures. Yet, for the solutions proposed thus far, the measurement speed has not increased proportionally to the number of channels, reducing the benefits of a multichannel approach. Recent theoretical studies and prototypes have shown that it is possible to implement a new multichannel architecture, so-called router-based architecture, capable of optimizing the efficiency of data transfer from the integrated chip to the data processor, increasing the overall measurement speed. However, the first implementations failed to achieve the theoretical results due to implementation flaws. In this paper, we present a new logic for the router-based architecture that can operate at the same laser frequency and solve the issues of the previous implementation. Alongside the new logic, we present a new integrated low-jitter delay line combined with a new method for timing-signal distribution that allows the proper management of the pixel timing information. The new implementation is a step closer to realizing a router-based architecture that achieves the expected theoretical results. Simulations and bench tests support the results here reported.

Title: Photon number resolution using sinusoidal wave-gated InGaAs/InAlAs single photon avalanche diode
Authors: Yi-Shan Lee
Affiliation: National Tsing Hua University
Abstract: We demonstrate the photon number-resolving (PNR) capability by utilizing the inherent gain of an InGaAs/InAlAs single-photon avalanche diode (SPAD) gated by a sinusoidal wave. In this work, the operating window can be adjusted by changing the gating frequency. A higher gating frequency results in a narrower gate window, improving the discrimination ability of PNR. Conversely, a lower gating frequency increases photon detection efficiency, thereby enhancing PNR in terms of higher photon number capacity. Moreover, the sinusoidal gating scheme can regulate the amount of avalanche carriers by adjusting the DC voltage level, the amplitude of the sinusoidal wave, and the gating frequency, providing flexibility in optimizing PNR.
