TL;DR: An overview of the most recent developments and improvements to the low-loss TriPleX Si3N4 waveguide technology is presented in this article, which can be combined to design complex functional circuits, but more important are manufactured in a single monolithic flow to create a compact photonic integrated circuit.

TL;DR: A reconfigurable 8×8 integrated linear optical network based on silicon nitride waveguides for quantum information processing based on a novel optical architecture enabling any arbitrary linear transformation and constitutes the largest programmable circuit reported so far on this platform.

TL;DR: In this article, a hybrid integrated diode laser source with feedback from low-loss silicon nitride (Si3N4 in SiO2) circuits is presented, achieving sub-100-Hz-level intrinsic linewidths, up to 120 nm spectral coverage around a 1.55 μm wavelength, and an output power above 100 mW.

TL;DR: In this article, a reconfigurable 8x8 integrated linear optical network based on silicon nitride waveguides for quantum information processing is presented. But the architecture is not scalable.

TL;DR: In this paper, a universal, reconfigurable, 8×8 photonic processor based on Si3N4 waveguides is presented for quantum information processing (QIP).
