Assisted by the rapid development of photonic integrated circuits, scalable and versatile chip-
based quantum light sources with nonlinear optics are increasingly tangible for real-world …

Multimode devices and components have attracted considerable attention in the last years,
and different research topics and themes have emerged very recently. The multimodality can …

We review the current status of mode-division multiplexing (MDM) techniques in fibers and
on chips. Three system applications are introduced, including quasi-single mode …

The overall goal of photonics research is to understand and control light in new and richer
ways to facilitate new and richer applications. Many major developments to this end have …

The ability to determine the joint spectral properties of photon pairs produced by the
processes of spontaneous parametric downconversion (SPDC) and spontaneous four-wave …

The purpose of this tutorial paper is to present a broad overview of photon-pair generation
through the spontaneous four wave mixing (SFWM) process in optical fibers. Progress in …

With growing interest in the spatial dimension of light, multimode fibers, which support
eigenmodes with unique spatial and polarization attributes, have experienced resurgent …

Photons occupying multiple spatial modes hold a great promise for implementing high-
dimensional quantum communication. We use spontaneous four-wave mixing to generate …

We describe a scheme for generation of spatial-mode-entangled photon pairs in a few-mode
fiber and experimentally demonstrate generation of idler beams from classical seed signals …
