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 …

Currently, perovskite solar cells (PSCs) with high performances greater than 20% contain
bromine (Br), causing a suboptimal bandgap, and the thermally unstable methylammonium …

Tailored quantum states of light can be created via a transfer of collective quantum states of
matter to light modes. Such collective quantum states emerge in interacting many-body …

Photon-pair sources are critical building blocks for photonic quantum systems. Leveraging
Kerr nonlinearity and cavity-enhanced spontaneous four-wave mixing, chip-scale photon …

This review article focuses on biphoton sources based on the double‐Λ Λ spontaneous four‐
wave mixing (SFWM) process in laser‐cooled as well as room‐temperature or hot atomic …

Non-classical photon sources are a crucial resource for distributed quantum networks.
Photons generated from matter systems with memory capability are particularly promising …

We report the generation of biphotons, with a temporal full width at the half maximum
(FWHM) of 13.4±0.3 µs and a spectral FWHM of 50±1 kHz, via the process of spontaneous …

Narrowband single photons that couple well to atomic ensembles could prove essential for
future quantum networks, but the efficient generation of such photons remains an …

We systematically studied the relation between the conditional auto-correlation function
(CACF) and cross-correlation function (CCF) of biphotons or pairs of single photons. The …

Biphotons, generated from a hot atomic vapor via the process of spontaneous four-wave
mixing (SFWM), have the following merits: Stable and tunable frequencies as well as …
