Comparison of non classical effects: quantum phase fluctuation, antibunching and minimum total noise in various non linear optical processes

Abstract

We study various non classical effects of light like reduction of quantum phase fluctuation, antibunching and minimum total noise present in various nonlinear optical processes. Further, we have shown that depth of non-classicality can be directly measured using all these parameters. We have done the comparative study to correlate these non-classical effects in seven wave mixing, eight wave mixing and third harmonic generation.

Study of nonclassicality in fifth harmonic generation nonlinear optical process

“…Equations (29)(30)(31)(32) show that neither normal antibunching nor higher order antibunching is present in pump mode A with respect to the quantum state |0 |β . Now using equations (12, 13 and 23) in equation ( 6), we get:…”

“…These two nonclassical effects may have lower and higher order renditions, investigation of lower order nonclassicality in a quantum state is accounted for in writing since its origin, yet premium in higher order is generally new and promising from an experimental perspective [27]. Out of these higher order nonclassical impacts, higher order squeezing has been focused on in detail [28][29][30][31] yet higher order sub-Poissonian photon statistics (HOSPS) and higher order antibunching (HOA) has not yet been concentrated definitely. The concept of HOA was introduced by Lee [32] and it has been anticipated in a two photon coherent state [32,33,33], and a shadowed negative binomial state [34].…”
