Abstract
- The quantum entanglement of amplitude and phase quadratures between two intense optical beams with a total intensity of 22mW and a frequency difference of 1nm, which are produced from an optical parametric oscillator operating above threshold, is experimentally demonstrated with two sets of unbalanced Mach-Zehnder interferometers. The measured quantum correlations of intensity and phase are in reasonable agreement with the results calculated based on a semiclassical analysis of the noise characteristics given by Fabre [J. Phys. (France) 50, 1209 (1989)].
