Alteration in Non-Classicality of Light on Passing Through a Linear Polarization Beam Splitter

TL;DR

This paper demonstrates how polarization squeezing can be generated and controlled by passing a mixture of two-mode squeezed vacuum and coherent light through a linear polarization beam splitter, revealing changes in non-classicality.

Contribution

It shows that superposing a two-mode squeezed vacuum with coherent light produces polarization-squeezed states with tunable squeezing properties using a linear polarization beam splitter.

Findings

All three Stokes parameters are squeezed at the output.

Squeezing depends on the parameters of the coherent light.

Polarization squeezing can be achieved even when the initial squeezed vacuum is not polarization-squeezed.

Abstract

We observe the polarization squeezing in the mixture of a two mode squeezed vacuum and a simple coherent light through a linear polarization beam splitter. Squeezed vacuum not being squeezed in polarization, generates polarization squeezed light when superposed with coherent light. All the three Stokes parameters of the light produced on the output port of polarization beam splitter are found to be squeezed and squeezing factor also depends upon the parameters of coherent light.
