Phys. Rev. A 72, 053805 (2005) [6 pages]Bright tripartite entanglement in triply concurrent parametric oscillationReceived 17 May 2005; published 4 November 2005 We show that an optical parametric oscillator based on three concurrent χ(2) nonlinearities can produce, above threshold, bright output beams of macroscopic intensities which exhibit strong tripartite continuous-variable entanglement. We also show that there are two ways that the system can exhibit a three-mode form of the Einstein-Podolsky-Rosen paradox, and calculate the extracavity fluctuation spectra that may be measured to verify our predictions. © 2005 The American Physical Society URL:
