We implement an ultrafast pulsed type-II parametric down conversion source in a
periodically poled KTP waveguide at telecommunication wavelengths with almost identical …

We study both experimentally and theoretically the generation of photon pairs by
spontaneous four-wave mixing (SFWM) in standard birefringent optical fibers. The ability to …

A fiber temperature sensor based on four-wave mixing (FWM) with an oil-filled photonic
crystal fiber (PCF) is proposed in this study, and a multipoint measurement based on the …

We analyse how imperfections in single-photon detectors impact the characterization of
photon-pair sources. We perform exact calculations to reveal the effects of multi-pair …

In this paper, a compact temperature sensor was constructed based on controllable four-
wave mixing (FWM) achieved by a partially filled solid-core photonic crystal fiber (PCF). With …

We present an all-fiber source of frequency-entangled photon pairs by using four-wave
mixing in a Sagnac fiber loop. Special care is taken to suppress the impurity of the frequency …

Four-photon scattering in nonlinear waveguides is an important physical process that allows
photon-pair generation in well-defined guided modes, with high rate and reasonably low …

Starting from the derived expression of the Bogoliubov transformation for a broadband
pulsed pump, we theoretically characterize the heralded single-photon source, which is …

We experimentally demonstrate a Hong-Ou-Mandel type of two-photon interference effect
with a heralded single-photon state and a thermal state. The light sources in the 1550 nm …

Correlated signal and idler photon pairs with small detuning in the telecom band can be
generated through spontaneous four-wave mixing in dispersion shift fibers. However …
