Multipartite entanglement in the optical frequency comb of a depleted-pump optical parametric oscillator
Reihaneh Shahrokhshahi, Olivier Pfister · 2011
We study the effect of pump depletion in a single type-I optical parametric oscillator (OPO) and find that pump-mediated, signal-field quantum correlations generate multipartite entanglement in the optical frequency comb of the OPO.
