Quantum analysis of a beam splitter with second-order nonlinearity and generation of nonclassical light
Hari Prakash, Devendra Kumar Mishra · Journal of the Optical Society of America B · 2016
A quantum mechanical model of a beam splitter having second-order nonlinearity is proposed and shows that nonclassical features such as squeezing and sub-Poissonian photon statistics of optical fields can be generated in output second-harmonic mode when we mix coherent light beams via such a nonlinear beam splitter.
