Increased Cross-Correlation in Cascaded Four-Wave Mixing Processes



Jingyun Fan, Alan L. Migdall, L Wang


We report the measurement of increased noise cross-correlation between stokes and anti-stokes beams created in cascaded four-wave mixing processes with dual pump wavelengths, when two-photon light is efficiently created at the middle frequency. This method may be useful in creating highly correlated twin beams for various applications including quantum information processing.
