The biphoton correlation time, a measure for the conditional uncertainty in the temporal
arrival of two photons from a photon pair source, is a key performance identifier for many …

All-optical wavelength conversion based on four-wave mixing attracts intense interest in
many areas, especially in optical fiber communications, due to the advantages of …

Quantum entanglement is an integral part of quantum optics and has been exploited in
areas such as computation, cryptography and metrology. The entanglement between …

We study both theoretically and experimentally the interference pattern in a nonlinear Mach–
Zehnder interferometer formed by two aperiodically-poled crystals, where broadband …

In this Letter, we report a polarization-entangled photon-pair source based on type-II
spontaneous parametric downconversion at telecom O-band in periodically poled silica fiber …

Dispersion plays a major role in the behavior of light inside photonic devices. Current state-
of-the-art dispersion measurement techniques utilize linear interferometers that can be …

Since the first proof-of-principle experiments 25 years ago, quantum metrology has matured
from fundamental concepts to versatile and powerful tools in a large variety of research …

Entangled photons are a fundamental resource in quantum applications. Broadband
entangled photon sources have been used in applications such as high-resolution quantum …

We present the generation of strong parametric fluorescence based on the spontaneous four-
wave mixing in a highly-nonlinear silicon nitride waveguide pumped by a simple C-band …

We demonstrate spectral and temporal interferometry using a SU (1, 1) interferometer based
on ultra-broadband, non-degenerate dispersion-engineered parametric down-conversion in …
