TL;DR: In this article, a photon-pair source based on spontaneous four wave mixing (SFWM) was designed and implemented in a few-mode fiber, in a geometry which permits multiple, simultaneous SFWM processes, each associated with a distinct combination of transverse modes for the four participating waves.

TL;DR: In this article, a few-mode, birefringent fiber was used to generate photon pairs through spontaneous four-wave mixing (SFWM) in the weakly guiding regime, for which the propagation modes may be well approximated by linearly polarized modes.

TL;DR: In this paper, three different mechanisms designed to controllably tune the joint spectrum of photon pairs produced by the spontaneous four-wave mixing (SFWM) process in optical fibres are explored.

TL;DR: SFWM spectra are presented, obtained through single-channel and coincidence photon counting, which exhibit multiple peaks shown here to be the result of multiple SFWM processes associated with different combinations of transverse modes for the pump, signal, and idler waves.

TL;DR: In this article, the photon pairs generated by spontaneous four wave mixing (SFWM), based on birefringent phasematching, in a fiber which supports more than one transverse mode were analyzed.
