We show theoretically that multipartite entanglement is generated on amassive scale in the spectrum, or optical frequency comb, of a single opticalparametric oscillator (OPO) emitting well above threshold. In this system, thequantum dynamics of the strongly depleted pump field are responsible for theonset of the entanglement by correlating the two-mode squeezed,bipartite-entangled pairs of OPO signal fields. (Such pairs are independent ofone another in the undepleted, classical pump approximation.) We verify themultipartite nature of the entanglement by evaluating the van Loock-Furusawacriterion for a particular set of entanglement witnesses deduced from physicalconsiderations.
