TL;DR: In this article, the authors fabricate polycrystalline anatase TiO2 microring resonators with loaded quality factors as high as 25,000 and average losses of 0.58 dB/mm in the telecommunications band.

TL;DR: Using sub-micrometer-wide polycrystalline anatase TiO₂ waveguides, third-harmonic generation on a CMOS-compatible platform is demonstrated and higher conversion efficiencies are correlated with phase-matching between the fundamental pump mode and higher-order signal modes.

TL;DR: The use of integrated nanophotonics to enhance nonlinear interactions and protocols to design multimode waveguides that enable sustained phase-matching for third-order spontaneous parametric down-conversion (TOSPDC) are developed.

TL;DR: In this paper, the present teachings are generally directed to devices and methods for triplet photons generations, and in particular to on-chip integrated sources for generating direct triplet entangled photons.

TL;DR: This work combines conventional Langmuir phase analysis with a novel dynamic viscoelasticity measurement to simply and accurately observe the jamming transition of monolayers of silica spheres, graphene oxide, and surfactant and shows how overcompressing beyond this point can modify the surface roughness of deposited films.
