Generation of squeezed states of light: A critical discussion

Rafael Julius, Mohammad Zulkarnain Khan Bin Zulkifpeli, Abdel-Baset M.A. Ibrahim

The generation of squeezed light across dual octaves with single-mode multichannel nonlinear waveguides exhibits dynamic behavior. In this study, we examine the impact of coherent state initialization, channel interaction, nonlinearity strength, and inter-channel interaction on the generation of squeezed light over several channels. The findings demonstrate that the process of coherent state initialization and the addition of channel interaction significantly enhance the amount of squeezing, hence emphasizing their critical role in the optimization of squeezed light generation. Additionally, an occurrence of squeezing that is not dependent on nonlinearity is observed within a limited range of parameters. This presents opportunities for generating squeezed light in dual-octave systems with many channels.

We study the generation of atomic-squeezed states for a Bose-Einstein Condensate confined within the lossless optomechanical cavity using pondermotively squeezed light. We show that the radiation pressure coupling between the optical cavity field and mechanical motion of the cavity end mirror generates squeezing of light. This radiation pressure induced light squeezing gets transferred to the condensate atoms via Tavis-Cummings type interaction and results in squeezed-spin states. We further discuss the effect of optomechanical coupling on squeezed atomic states.

In this paper we review the current state of progress in research on squeezed light. We discuss the basic theory of squeezing and the nature of quantum noise in optical fields. We examine various atomic sources of squeezed light and discuss phase-sensitive detectors of quantum noise including homodyne and heterodyne detectors. Various successful nonlinear optical methods for generating squeezed light are reviewed. We conclude with a discussion of the possible applications of squeezed light.
