Fast data-driven spectrometer with direct measurement of time and frequency for multiple single photons
arxiv(2023)
摘要
We present a single-photon-sensitive spectrometer, based on a linear array of
512 single-photon avalanche diode detectors, with 0.04 nm spectral and 40 ps
temporal resolutions. We employ a fast data-driven operation that allows direct
measurement of time and frequency for simultaneous single photons, time- and
frequency-stamping each single-photon detection. Our results combine excellent
temporal and spectral resolution. We benchmark our result against the
Heisenberg Uncertainty Principle limit of hbar/2 for time and energy, and we
are only a factor of 10 above it, despite the simplicity of our experimental
setup, including room temperature operation. This work opens numerous
applications in both classical and quantum photonics, especially when both
spectral and temporal properties of single photons are exploited.
