Abstract-Photon counting applications are typically limited by detector deadtime to operate at count rates of a few MHz, at best, and often at significantly lower levels. This limitation is becoming more critical with the advance of photon counting applications such as photon-based quantum information. We present a first experimental proof of principle and review the theoretical foundation of a multiplexed detection scheme that allows photons to be counted at higher rates than is possible with individual detectors or simple detector trees. In addition to this deadtime improvement, we discuss the impact of this scheme on other relevant characteristics such as afterpulsing and dark count rates.Index Terms-photon counting, multiplexing, InGaAs single photon avalanche detector, parametric down-conversion, fast fiber switch.

“…Owing to progressive pulse overlapping for increasing flux intensity, the measured number of pulses is lower than the real number. It is shown in Castelletto et al (2007) that the loss in counts N − N = NN k ∆t N . Knowing that S net = N ∆t N by definition, the counting loss can easily be reformulated and the relation between S net and S raw in Eq.…”

Context. The SOLar SPECtrum (SOLSPEC) experiment is part of the Solar Monitoring Observatory (SOLAR) payload, and has been externally mounted on the Columbus module of the International Space Station (ISS) since 2008. SOLAR/SOLSPEC combines three absolutely calibrated double monochromators with concave gratings for measuring the solar spectral irradiance (SSI) from 166 nm to 3088 nm. This physical quantity is a key input for studies of climatology, planetary atmospheres, and solar physics. Aims. A general description of the instrument is given, including in-flight operations and performance of the ultraviolet (UV) channel from 175 nm to 340 nm. Methods. We developed a range of processing and correction methods, which are described in detail. For example, methods for correcting thermal behavior effects, instrument linearity, and especially the accuracy of the wavelength and absolute radiometric scales have been validated by modeling the standard uncertainties. Results. The deliverable is a quiet Sun UV reference solar spectrum as measured by SOLAR/SOLSPEC during the minimum of solar activity prior to cycle 24. Comparisons with other instruments measuring SSI are also presented.

“…On the side of sources, a possible generator of correlated photons comes from the development of χ (3) single-mode photonic fiber-based sources with pair rates up to 10 7 s −1 , with very low input pump power [16,17]. Finally to improve the possible measurable rate in the photon counting regime, a scheme made of a pool of photon-counting detectors operating as a unit could be used [83,84] with better accuracy. The proposed scheme consists of a 1-by-N optical switch that takes a single input stream of photons and distributes them to members of an array of N detectors.…”

Abstract. Single photon counting, based on single photon sources and detectors, is a key ingredient for certain applications aiming at new quantum information technologies. Quantum cryptography, quantum radiometry, distributed quantum computing, as well as adjacent technologies such as biomedical and astronomical imaging, and low power classical communication also rely on single-photon technology. This paper reviews the present status of single photon sources and related counting measurement techniques, based on correlated (or heralded) photons in parametric down-conversion, and their possible impact on the above mentioned technologies, as well as an assessment for photon standards in the future.
