“…Higher-order non-classicality, as the name implies, refers to the non-classical characteristics revealed by higher order correlations. Higher order photon antibunching (HOA) [6], higher-order sub-Poissonian photon number statistics (HOSPS) [7,8], higher order squeezing of Hong-Mandel type [9,10] are the most often researched higher order non-classical characteristics. All of these non-classical characteristics have lower order equivalents that have been well investigated [11,12].…”

We have studied non-classical effects, i.e. higher order photon antibunching (HOA) and higher order sub-Poissonian photon number statistics (HOSPS) in various non-linear optical processes like second harmonic generation, fourth harmonic generation, coherent anti-Stokes Raman scattering (CARS) and coherent anti-Stokes hyper-Raman scattering (CAHRS) using short time interaction techniques. The non-classical effects directly depend on number of photons prior to interaction with non-linear medium has already been studied but we have found that non-linear processes involving equal number of pump photons have same higher order photo antibunching (HOA) and higher order sub-Poissonian photon number statistics (HOSPS) independent of the non-linear process involved. KEYWORDS Higher order sub-Poissonian photon number statistics, higher order photon antibunching, optical processes.
