Abstract
We have theoretically analysed the effect of polarization of the initial state on squeezed-state generation. The analysis has been applied to a sample of GaAs irradiated by a KCl:Na laser tunable over the range 1.62-1.91 µm. The ellipticity of error ellipse and time and power dependence of quadrature variance suggest that the circular polarization state is most suitable for squeezed-state generation. We have also extended our analysis to a homodyne detection technique and have studied the power dependence of signal-to-noise ratio.
