Measuring absolute spectral radiance using an Erbium Doped Fibre Amplifier
Bruno Sanguinetti, Thiago Guerreiro, Fernando Monteiro +2
We describe a method to measure the spectral radiance of a source in an absolute way without the need of a reference. Here we give the necessary detail to allow for the device to b…
Advantages of gated silicon single photon detectors
T. Lunghi, E. Pomarico, C. Barreiro +3
We present a gated silicon single photon detector based on a commercially available avalanche photodiode. Our detector achieves a photon detection efficiency of 45\pm5% at 808 nm w…
Retinal and post-retinal contributions to the quantum efficiency of the human eye
Gibran Manasseh, Chloe de Balthasar, Bruno Sanguinetti +4
The retina is one of the best known quantum detectors with rods able to respond to a single photon. However, estimates on the number of photons eliciting conscious perception, base…
MHz rate and efficient synchronous heralding of single photons at telecom wavelengths
Enrico Pomarico, Bruno Sanguinetti, Thiago Guerreiro +2
We report on the realization of a synchronous source of heralded single photons at telecom wavelengths with MHz heralding rates and high heralding efficiency. This source is based…
Single-photon space-like antibunching
Thiago Guerreiro, Bruno Sanguinetti, Hugo Zbinden +2
We use heralded single photons to perform an antibunching experiment in which the clicks at the detectors are spacelike separated events. The idea of such experiment dates back to…
