Squeezed state generation and nonclassical correlations in nondegenerate parametric down conversion

Abstract

We report observations of squeezed state generation in a subthreshold optical parametric oscillator (OPO) operated in a frequency degenerate but polarization nondegenerate mode. Reductions in photocurrent fluctuations of-4 dB relative to the vacuum-state or shot-noise limit have been recorded with a balanced homodyne receiver. We have as well investigated a possible realization of the Einstein-Podolsky-Rosen paradox involving the nonclassical correlations of quadrature phase amplitudes for the orthogonally polarized signal and idler fields.
