Photonic integrated circuits with second-order (χ (2)) nonlinearities are rapidly scaling to
remarkably low powers. At this time, state-of-the-art devices achieve saturated nonlinear …

This article reviews recent progress in quasi-phasematched χ (2) nonlinear nanophotonics,
with a particular focus on dispersion-engineered nonlinear interactions. Throughout this …

The strength of interactions between photons in a χ^(2) nonlinear optical waveguide
increases at shorter wavelengths. These larger interactions enable coherent spectral …

<? TeX 2pc 0pt?> We study the emergence of non-Gaussian quantum features in pulsed
squeezed light generation with a mesoscopic number (ie, dozens to hundreds) of pump …

Ultrashort pulses propagating in nonlinear nanophotonic waveguides can simultaneously
leverage both temporal and spatial field confinement, promising a route towards single …

The large-photon-number quantum state is a fundamental but nonresolved request for
practical quantum information applications. We propose an N-photon state generation …

In broadband quantum optical systems, nonlinear interactions among a large number of
frequency components induce complex dynamics that may defy heuristic analysis. In this …

High-efficiency photon-pair production is a long-sought-after goal for many optical quantum
technologies, and coherent photon conversion (CPC) processes are promising candidates …

The advent of dispersion-engineered and highly nonlinear nanophotonics is expected to
open up an all-optical path towards the strong-interaction regime of quantum optics by …
