We show theoretically and experimentally that scattered light by thermal phonons inside a
second-order nonlinear crystal is the source of additional phase noise observed in optical …

We investigate interesting symmetry properties verified by the down-converted beams
produced in optical parametric amplification with structured light. We show that the Poincaré …

We show that scalable multipartite entanglement among light fields may be generated by
optical parametric oscillators (OPOs). The tripartite entanglement existent among the three …

In this paper we consider frequency translation enabled by Bragg scattering, a four-wave
mixing process. First we introduce the theoretical background of the Green function …

We experimentally investigate quadrature correlations between pump, signal, and idler
fields in an above-threshold optical parametric oscillator. We observe new quantum …

In this paper, tripartite entanglement among the two pump fields and the second-order
harmonic field is established in the process of type-II second-order harmonic generation …

Multipartite entanglement is a resource for quantum communication and computation. Vector
four-wave mixing (FWM) in a fiber, driven by two strong optical pumps, couples the evolution …

We use a versatile model to evaluate the multipartite entanglement and the nonclassical
light generation in optical parametric oscillators, exploring the differences between doubly …

The bright two-color tripartite entanglement is investigated in the process of type II second
harmonic generation (SHG) operating above threshold. The two pump fields and the second …

Three-colour continuous-variable entanglement produced by single-pass cascaded quasi-
phase-matching fourth harmonic generation is investigated. The fourth harmonic can be …
