TL;DR: In this article, a few-layer WS2 flake of ∼14.8 μm length was transferred to a dispersion-engineered silicon nitride waveguide and an effective nonlinear coefficient higher than 600 m-1 W-1 was retrieved for the heterogeneous waveguide indicating an enhancement factor of larger than 300 with respect to the pristine waveguide at a wavelength of 800 nm.

TL;DR: In this article, the authors proposed a general approach to stretch the bandwidth of Kerr frequency combs based on subwavelength engineering of single-mode waveguides with self-adaptive boundaries.

TL;DR: In this article, a self-adaptive boundary of the optical mode at different wavelengths in a sub-wavelength structured waveguide is proposed to trim frequency combs using a selfadaptive variation on the confinement.

TL;DR: In this paper, the authors demonstrate enhanced optical Kerr modulation in hybrid silicon nitride/gallium sulfide microring resonators, which is a van der Waals material with strong optical nonlinearities.
