Abstract. Since the introduction of higher order nonclassical effects, higher order squeezing has been reported in a number of different physical systems but higher order antibunching is predicted only in three particular cases. In the present work, we have shown that the higher order antibunching is not a rare phenomenon; rather it can be seen in many simple optical processes. To establish our claim, we have shown it in the six wave mixing process, four wave mixing process and second harmonic generation process.
