Minimum Total Noise in Wave-Mixing Processes

Minimum Total Noise in Wave-Mixing Processes

Higher-order squeezing in different optical processes such as seven-wave mixing and five-wave mixing has been studied. The total noise of a field state is a measure of the fluctuations of the field amplitude. It is shown that the minimum total noise (Tmin) of a higher-order squeezed state always inc...

The total noise of a field state is a measure of the fluctuations of the field amplitude. It is shown that the minimum total noise (Tmin) of a higher-order squeezed state always increases with the increase in nonclassicality associated with higher-order squeezing. Thus, from Tmin, one can conclude that highly nonclassical states have large amplitude fluctuations.http://dx.doi.org/10.1155/2012/431826
