Quantum imaging is a multifaceted field of research that promises highly efficient imaging in
extreme spectral ranges as well as ultralow‐light microscopy. Since the first proof‐of …

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 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 …

Optical nonlinear conversion processes are ubiquitously applied to scientific as well as
industrial tasks. In particular, nonlinear processes are employed to generate radiation in …

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 …

Interest in the nonlinear properties of multi-mode optical waveguides has seen a recent
resurgence on account of the large dimensionality afforded by the platform. The large …

We experimentally demonstrate frequency non-degenerate photon-pair generation via
spontaneous four-wave mixing from a novel CS2-filled microstructured optical fiber. CS2 has …

In this paper, we present a design of an all-fiber source of correlated photon pairs based on
standard telecommunications tapered fibers. We examine the generation of correlated …

We design, fabricate and test an integrated silicon photonics chip for inter-modal four wave
mixing, whose phase-matching relays on the modal dispersions of different waveguide …
