“…The difference in arrival time between the photon pairs at the BS is adjusted through a motorized delay line constructed in one of the paths. Upon exiting the BS, the photons are coupled into single mode optical fibers which are then fed into the customized spectrometer [23][24][25].…”

In this work we demonstrate spectral-temporal correlation measurements of the Hong-Ou-Mandel (HOM) interference effect with the use of a 3D (2 spatial + 1 time dimension) camera based spectrometer. This setup allows us to take, within seconds, spectral temporal correlation measurements on entangled photon sources with sub-nanometer spectral resolution and nanosecond timing resolution. Through post processing, we can observe the HOM behaviour for any number of spectral filters of any shape and width at any wavelength over the observable spectral range. Our setup also offers great versatility in that it is capable of operating at a wide spectral range from the visible to the near infrared and does not require a pulsed pump laser for timing purposes. This work offers the ability to gain large amounts of spectral and temporal information from a HOM interferometer quickly and efficiently and will be a very useful tool for many quantum technology applications and fundamental quantum optics research.

“…The MCP in the intensifier has an improved detection efficiency close to 100%. Similar configurations of the intensified Tpx3Cam were used before for characterization of quantum networks [18,19], quantum target detection [20,21], single photon counting [22] and lifetime imaging [23] studies.…”

Novel imaging technique for α-particles using a fast optical camera

et al. 2021

A: A new imaging technique for α-particles using a fast optical camera focused on a thin scintillator is presented. As α-particles interact in a thin layer of LYSO fast scintillator, they produce a localized flash of light. The light is collected with a lens to an intensified optical camera, Tpx3Cam, with single photon sensitivity and excellent spatial & temporal resolutions. The interactions of photons with the camera is reconstructed by means of a custom algorithm, capable of discriminating single photons using time and spatial information.

“…An efficient scheme of spectroscopic binning can be implemented by employing a traditional diffraction grating spectrometer where incoming photons are passed though a slit, dispersed, and then focused onto a linear array of single-photon detectors. In our previous work we implemented spectroscopic binning employing a fast pixel camera [10,11] and determined the temporal and spectroscopic resolutions for pairs of registered photons in the context of quantum target detection [12,13]. We achieved ∆t • ∆λ = 5 ns • 0.5 nm at 800 nm representing a useful benchmark for current technology.…”
