“…electron-hole pair generation and the photoelectric effect, exploiting superconductivity instead. They have been developed and used for astronomical applications, as reviewed recently [151], but some of these detectors have also been used for the detection of instrumental responses of laser pulses and fluorescence decays via TCSPC [152,153].…”

“…For example, InGaAs/ InP SPADs have detection efficiencies greater than 10% at 1550 nm, but suffer from high dark count rates and the deleterious effects of afterpulsing, which generally result in a need for both gated operation and much reduced overall count rates [11] compared with Si-based SPADs. In this Letter we present ranging results obtained with a nanopatterned superconducting single-photon detector (SSPD), which has demonstrated single-photon sensitivity at longer wavelengths with lower jitter of 68 ps FWHM and a Gaussian profile [12]. We estimate the minimum resolvable surface separation using the same approach employed previously [10].…”

We demonstrate subcentimeter depth profiling at a stand off distance of 330 m using a time-of-flight approach based on time-correlated single-photon counting. For the first time to our knowledge, the photoncounting time-of-flight technique was demonstrated at a wavelength of 1550 nm using a superconducting nanowire single-photon detector. The performance achieved suggests that a system using superconducting detectors has the potential for low-light-level and eye-safe operation. The system's instrumental response was 70 ps full width at half-maximum, which meant that 1 cm surface-to-surface resolution could be achieved by locating the centroids of each return signal. A depth resolution of 4 mm was achieved by employing an optimized signal-processing algorithm based on a reversible jump Markov chain Monte Carlo method.

“…The first practical application of these detectors was for non-invasive testing and debugging of CMOS integrated circuits [13,14], while recently, they were implemented for fast lifetime measurements of quantum well structures emitting IR radiation [15], and for determination of spontaneous emission lifetimes of InAs quantum dot single photon sources [3]. Our SSPDs are also very attractive for QC protocols due to low dark counts, in combination with the fast recovery time, and hence, high maximal counting rate [16].…”

We have fabricated fiber-coupled superconducting single-photon detectors (SSPDs), designed for quantum-correlationtype experiments. The SSPDs are nanostructured (~100-nm wide and 4-nm thick) NbN superconducting meandering stripes, operated in the 2 to 4.2 K temperature range, and known for ultrafast and efficient detection of visible to nearinfrared photons with almost negligible dark counts. Our latest devices are pigtailed structures with coupling between the SSPD structure and a single-mode optical fiber achieved using a micromechanical photoresist ring placed directly over the meander. The above arrangement withstands repetitive thermal cycling between liquid helium and room temperature, and we can reach the coupling efficiency of up to ~33%. The system quantum efficiency, measured as the ratio of the photons counted by SSPD to the total number of photons coupled into the fiber, in our early devices was found to be around 0.3 % and 1% for 1.55 µm and 0.9 µm photon wavelengths, respectively. The photon counting rate exceeded 250 MHz. The receiver with two SSPDs, each individually biased, was placed inside a transport, 60-liter liquid helium Dewar, assuring uninterrupted operation for over 2 months. Since the receiver's optical and electrical connections are at room temperature, the set-up is suitable for any applications, where single-photon counting capability and fast count rates are desired. In our case, it was implemented for photon correlation experiments. The receiver response time, measured as a second-order photon cross-correlation function, was found to be below 400 ps, with timing jitter of less than 40 ps.
