چکیده
|
This paper describes the second-order coherence degree of photons produced in spdc. 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.
