Entangled photons exhibit strong nonclassical frequency and time correlations
simultaneously, which allow them to excite and extract information about molecules in new …

Raman-scattering noise in silica has been the key obstacle toward the realisation of high
quality fiber-based photon-pair sources. Here, we experimentally demonstrate how to get …

We report a bright and tunable source of spectrally pure heralded single photons in the
telecom O-Band, based on cross-polarized four wave mixing in a commercial birefringent …

In the same silicon photonic integrated circuit, we compare two types of integrated
degenerate photon-pair sources (microring resonators and waveguides) using Hong–Ou …

Tailoring wavelength correlations in fiber-optical sources through nonlinear phenomena
could drive many quantum optics applications. However, to date, such correlations have not …

Nowadays fiber biphoton sources are nearly as popular as crystal-based ones. They offer a
single spatial mode and easy integrability into optical networks. However, fiber sources lack …

Tunable biphotons are highly important for a wide range of quantum applications. For some
applications, especially interesting are cases where two photons of a pair are far apart in …

Laser sources in the short-and mid-wave infrared spectral regions are desirable for many
applications. The favorable spectral guidance and power handling properties of an inhibited …

In this paper, we describe experimental observation and characterization of emission of
photon pairs through four-wave mixing (FWM) in a silica nanofiber, with high coincidence to …

In this paper, we numerically and experimentally investigate the four-wave mixing process in
a gas-filled hollow-core capillary in the femtosecond regime. The interaction between a …
