The Impact

Single-photon detection concept is the most crucial and often difficult factor to determine the performance of quantum key distribution (QKD) systems. One solution to facilitate understanding this concept is to create a virtual environment for modeling, analyzing, and investigating the performance of single photon detectors. In this paper, a simulator for superconducting single photon detectors with time domain visualizer and configurable parameters is presented. The widely used ID281SNSPD in the QKD area was theoretically modeled in terms of pulse analysis, the impact of biasing current and the temperature on the dark counts rate and single photon-detection efficiency and influence of the number of photons per pulse on the single photon-detection efficiency. The simulated results were in good agreement with the theoretical results and the simulator demonstrated its adaptability.

We present overview of achieved results on 4H-SiC avalanche photodiodes (APDs) and arrays. Cost-effective solar-blind optical filter allows achieving high solar photon rejection ratio of more than 106 in combination with more than 40% single photon detection efficiency at 266nm. Three iterations of devices were fabricated and evaluated to compare their optical and electrical properties. Dark count rates and single photon detection efficiencies are the main characteristics compared for these three iterations of device designs.

Photon Detection Efficiency

Avalanche photodiodes are crucial materials for single-photon detection. Single-photon detectors are indispensable components for optical experiments and applications such as quantum information processing and quantum communications, both of which demand high single-photon detection efficiency. The authors have first developed a silicon single-photon avalanche detector in near infrared spectrum with 1 MHz square wave gating and tested its performance. Then we have also designed a high-speed and high-efficiency silicon single-photon detection system with 152 MHz sine wave gating and improved its single-photon detection efficiency to 77.48%.

Single Photon Detectors

Single-photon detection concept is the most crucial factor that determines the performance of quantum key distribution (QKD) systems. In this paper, a simulator with time domain visualizers and configurable parameters using continuous time simulation approach is presented for modeling and investigating the performance of single-photon detectors operating in Gieger mode at the wavelength of 830 nm. The widely used C30921S silicon avalanche photodiode was modeled in terms of avalanche pulse, the effect of experiment conditions such as excess voltage, temperature and average photon number on the photon detection efficiency, dark count rate and afterpulse probability. This work shows a general repeatable modeling process for significant performance evaluation. The most remarkable result emerged from the simulated data generated and detected by commercial devices is that the modeling process provides guidance for single-photon detectors design and characterization. The validation and testing results of the single-photon avalanche detectors (SPAD) simulator showed acceptable results with the theoretical and experimental results reported in related references and the device's data sheets.
