Detectors for SII
- Robin Kaiser (CNRS / Université de la Côte d’Azur)
Superconducting nanowire single-photon detectors (SNSPD) systems have progressed rapidly over the past decade. Recent devices exhibit leading performance figures including sub-10 ps system timing jitter, 1.5 GHz detection rates, arrays up to 400,000 pixels, sub-hertz dark count rates, high efficiency, as well as intrinsic and array-based photon number resolution. In this talk I will review...
Correlations of photon pairs from entangled quantum sources offer advantages and provide additional opportunities in new sensing approaches in multiple fields. In general, strong spectro-temporal correlations inherent for entangled photons could make those sensing techniques much more precise and resource efficient. In application to astrophysics I will compare the standard techniques of...
We present our simultaneous broadband multi-wavelength HBT measurement in a spectrometer with a 25 nm range, 0.1 nm/pixel scale based on the 512-pixel SPAD sensor of the LinoSPAD2 detector. Using an LED as a broadband source of light simulating starlight, we measure the HBT effect in tens of spectral bins. Detector resolution of 40 ps rms allows us to achieve 3% contrast in under 10 hours of...
