TL;DR: In this paper, the authors demonstrate an approach for automated Kerr comb generation in the normal group-velocity dispersion (GVD) regime using a coupled-ring geometry in silicon nitride, precisely controlling the wavelength location and splitting strength of avoided mode crossings.

TL;DR: This Letter demonstrates the generation of quadrature-phase squeezed states in the radio-frequency carrier sideband using a small-footprint silicon-nitride microresonator with a dual-pumped four-wave-mixing process and shows that it is critical to account for the nonlinear behavior of the pump fields to properly predict the squeezing that can be generated in this system.

TL;DR: The authors exploit χ nonlinearity in SiN to demonstrate on-chip phase-tunable coupling between two DOPO based Ising nodes, which can be deterministically achieved at a fast regeneration speed of 400 kHz with a large phase tolerance.

TL;DR: This work demonstrates the generation and coupling of two microresonator-based DOPO's on a single chip and achieves both in-phase and out-of-phase operation, which can be deterministically achieved at a fast regeneration speed of 400 kHz with a large phase tolerance.

TL;DR: In this article, a frequency-domain Hong-Ou-Mandel interference with spectrally distinct photons generated from a chip-based microresonator is reported. And the authors use four-wave mixing to implement an active frequency beam splitter and achieve interference visibilities of 0.95 and 0.02, respectively.
