All-fiber systems for third harmonic generation are of great interest because they can be
used for the inverse process, namely, the generation of entangled photon triplets. Usually …

We present an experimental proposal for the generation of photon triplets based on third-
order spontaneous parametric downconversion in thin optical fibers. Our analysis includes …

We study the third-order spontaneous parametric down-conversion (TOSPDC) process, as a
means to generate entangled photon triplets. Specifically, we consider thin optical fibers as …

Optical fibers have been considered an optimal platform for third-order parametric down-
conversion since they can potentially overcome the weak third-order nonlinearity by their …

Generation of entangled photons in nonlinear media constitutes a basic building block of
modern photonic quantum technology. Current optical materials are severely limited in their …

Linear quantum optics is advancing quickly, driven by sources of correlated photon pairs.
Multi-photon sources beyond pairs would be a powerful resource, but are a difficult …

The theory of third-order spontaneous parametric down-conversion (TOSPDC) in a ring
waveguide microcavity is developed. Analytical expressions for the rate of photon triplet …

We investigate the third-order spontaneous parametric down-conversion process in a
nonlinear media with inversion centers. Specifically, we analyze in details the three-photon …

Nondegenerate triple-photon parametric down-conversion (NTPD) is a potential source for
unconditional tripartite non-Gaussian entangled states of continuous variables. Recent …

Nonclassicality criteria for general N-dimensional optical fields are derived. They involve
intensity moments, the probabilities of photon-number distributions, or combinations of both …
