First, the nonlinear BBO crystal generates the twin correlated signal and idler photons in the experimental setup. Then, g2 (0) is obtained experimentally via Hanbury Brown-Twiss set-up for investigation of the light source nature. The results show this value is less than 1 which verifies the generated photons are in the heralded single photon (HSP) regime. %> http://ijop.ir/article-1-506-en.pdf %P 145-152 %& 145 %! %9 Research %L A-10-898-1 %+ Photonics and Quantum Technologies Research School, Nuclear Science and Technology Research Institute (NSTRI) %G eng %@ 1735-8590 %[ 2022
