Spectral Properties and Photon-Number Distribution of Highly-Nondegenerate Entangled Photons
Bochen Wang, Zhengyong Li · 2023
We obtain specific spectral properties of highly-nondegenerate entangled photons measured by photon-number-resolving detectors under different focusing schemes, and observe the distribution changing from Poissonian to thermal as wavelength leaving away from their peak.
