The afterpulse probability has been measured using the photon statistical method on the base of theoretical analysis for single-photon detection. It is found that the measured afterpulses obey Gaussian distribution, and the Gauss curves are left shifted with increasing incident photon intensity. We have analyzed the physical process of the phenomenon and obtained the afterpulse probability of our single-photon detector. Compared with the common start–stop method, this robust photon statistical method has the advantages of direct measurement and not requiring additional equipment.

<p class="zhengwen"><span lang="EN-GB">Light emitting diodes (LEDs) have applications in many industries for illumination. However, the LED is not limited to the generation of light. In this article, we demonstrate and analyze a low-cost LED for use as a single photon detector, rather than as an emitter. While many technologies have been developed for single photon detection, the focus has been on timing resolution and efficiency—not on cost of production. We compare our device to commercial solutions and validate the efficacy of active quenching to improve maximum photon count rate. While this device may be useful for labs requiring a large number of low-cost detectors, it can also serve as a teaching tool in advanced laboratory settings.</span></p>

In order to achieve non-cooperative target tracking and ranging in conditions of a weak echo signal, this paper presents a real-time acquisition, pointing, tracking (APT), and ranging (APTR) lidar system based on single photon detection. With this system, an active target APT mechanism based on a single photon detector is proposed. The target tracking and ranging strategy and the simulation of target APT are presented. Experiments in the laboratory show that the system has good performance to achieve the acquisition, pointing and ranging of a static target, and track a dynamic target (angular velocity around 3 mrad/s) under the condition of extremely weak echo signals (a dozen photons). Meanwhile, through further theoretical analysis, it can be proven that the mechanism has stronger tracking and detection ability in long distance. It can achieve the active tracking of the target with a lateral velocity of hundreds of meters per second at about one hundred kilometers distance. This means that it has the ability of fast long-distance non-cooperative target tracking and ranging, only by using a single-point single photon detector.

Single photon detection applied to optically stimulated luminescence (OSL) dosimetry is a promising approach due to the low level of luminescence light and the known statistical behavior of single photon events. Time resolved detection allows to apply a variety of different and independent data analysis methods. Furthermore, using amplitude modulated stimulation impresses time- and frequency information into the OSL light and therefore allows for additional means of analysis. Considering the impressed frequency information, data analysis by using Fourier transform algorithms or other digital filters can be used for separating the OSL signal from unwanted light or events generated by other phenomena. This potentially lowers the detection limits of low dose measurements and might improve the reproducibility and stability of obtained data. In this work, an OSL system based on a single photon detector, a fast and accurate stimulation unit and an FPGA is presented. Different analysis algorithms which are applied to the single photon data are discussed.

Geiger Mode

In this paper, we experimentally characterize the Inga As/Imp avalanche photodiode (APD), which is working in Geiger mode, so as to choose the single photon detector for quantum communication. Due to the fact that bias of APD tends to be flat after avalanche, we first adopt the methodology of passive quenching to determine dark breakdown voltage. Experiment results indicate that temperature reduction will widen the optimal operating region and increase the optimal multiplication; therefore APD will be more sensitive. Epitaxial APD is the best choice for single-photon detection among the APDs we have tested for its low noise level and high signal-to-noise ratio (SNR). Finally, we design a mixed passive-active quenching integrated circuit with gate control, which is quick with the quenching time of about 25ns and has controllable dead time with minimum of about 60ns.

AbstractA design for a high-efficiency single-photon detector based on lanthanum and cerium hexaborides, which operates from the infrared to ultraviolet spectral ranges, is suggested. The results of computer simulations of heat transfer in the sensitive element of the detector upon the absorption of photons with energies of 0.5–4.13 eV are presented. To attain a high efficiency of the system of photon detection in the wavelength range from near infrared to ultraviolet, lanthanum hexaboride is proposed as the absorber and heat-sink material in the sensitive element. It is shown that a sensitive element of both single- and three-layer design made entirely of hexaborides will possess a gigahertz counting rate and a detection efficiency exceeding 90%.
