Integrated optical components on lithium niobate play a major role in standard high-speed
communication systems. Over the last two decades, after the birth and positioning of …

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 …

Entangled photon pairs are a critical resource in quantum communication protocols ranging
from quantum key distribution to teleportation. The current workhorse technique for …

Practical quantum networking architectures are crucial for scaling the connection of quantum
resources. Yet quantum network testbeds have thus far underutilized the full capabilities of …

Flexible grid wavelength division multiplexing is a powerful tool in lightwave
communications to maximize spectral efficiency. In the emerging field of quantum …

We present the realization of a highly efficient photon pair source based on spontaneous
parametric downconversion (SPDC) in a periodically poled lithium niobate (PPLN) ridge …

As practical quantum networks prepare to serve an ever-expanding number of nodes, there
has grown a need for advanced auxiliary classical systems that support the quantum …

We report the possibility of achieving normal-incidence transmission at non-normal
incidence angles using thin interfaces made of metasurface structures with an appropriately …

We present a pulsed and integrated, highly non-degenerate parametric down-conversion
(PDC) source of heralded single photons at telecom wavelengths, paired with heralding …

We present an integrated source of polarization entangled photon pairs in the telecom
regime, which is based on type II-phasematched parametric down-conversion (PDC) in a Ti …
