Abstract

Recently, it was found [J. Phys. B: At. Mol. & Opt. Phys. 38, 665 (2005)] that amplitude-squared squeezing, a non-classical feature, can be enhanced during linear mixing with a coherent light beam using a symmetric lossless beam splitter. Here, another example is reported of enhancement of an easily detectable non-classical feature of an optical field in a similar mixing using a symmetric lossless beam splitter.
