Abstract
Evolution of the vacuum fluctuations in the two-wave mixing of the
optical fields propagating in the birefringent fibre is studied. The two-wave
mixing in the birefringent fibre has been suggested as a possible scheme for
the entangled state generation. Our treatment to study the entangled state
generation uses undepleted pump approximation and enables to trace influence
of input conditions of the classical optical fields on evolution of the
vacuum squeezing. We report the periodical modulation of the vacuum squeezing
when input relative phase of the coherent waves varies. Measure of
nonclassical correlations imposed on the generated light is calculated.
