Quantum sources that provide broadband biphotons entangled in both polarization and time-
energy degrees of freedom are a rich quantum resource that finds many applications in …

We demonstrate a wavelength-tunable, fiber-coupled source of polarization-entangled
photons with extremely high spectral brightness and quality of entanglement. Using a 25 mm …

We describe an achromatic, phase-stable, broadband source of polarization-entangled
photon pairs with high spectral brightness that uses four-wave mixing in a fiber Sagnac …

Studies on telecom-band entangled photon-pair sources for entanglement distribution have
so far focused on their narrowband operations. Fiber-based sources are seriously limited by …

We demonstrate a fiber-based source of polarization-entangled photon pairs at visible
wavelengths suitable for integration with local quantum-processing schemes. The photons …

We demonstrate a novel polarization-entangled photon-pair source based on standard
birefringent polarization-maintaining optical fiber. The source consists of two stretches of …

In this article, we report a compact, low-power laser diode-pumped, all-fiber polarization-
entangled photon pair source based on periodically-poled silica fiber technology. The all …

We demonstrate broadband polarization-entangled photon pair generation in a poled fiber
phase matched for Type II downconversion in the 1.5 μm telecom band. Even with signal …

We demonstrate a bright, narrowband, compact, quasi-phase-matched single-crystal source
generating path-polarization-entangled photon pairs at 810 nm and 1550 nm at a maximum …

We designed and implemented a novel combination of a Sagnac-interferometer with a Mach–
Zehnder interferometer for a source of polarization-entangled photons. The new versatile …
