TL;DR: This work demonstrates experimentally passive PT-symmetry breaking within the realm of optics, which leads to a loss induced optical transparency in specially designed pseudo-Hermitian guiding potentials.

TL;DR: In this article, a fully integrated, CMOS-compatible, multiple-wavelength source with high differential slope efficiency at only a few tens of milliwatts of continuous-wave power is presented.

TL;DR: In this paper, the authors present the first demonstration of nonlinear optics in integrated silica-based glass waveguides using continuous-wave light, and demonstrate four-wave mixing with low (5mW) continuous-Wave pump power at λ = 1,550nm, in high-index, doped silica glass ring resonators.

TL;DR: This work represents a practical on-chip broadband wavelength source with potential use in many important applications and is well reproduced by simulations based on the measured dispersion.

TL;DR: The high nonlinearity and low linear and nonlinear losses of these waveguides make them promising for nonlinear all-optical signal processing applications.
