The ring's four nodes feature erbium-doped waveguide amplifiers (EDWAs), shown here for the first time in cascade, which promise future integrability.

Samples were obtained from the melt and the RE concentration ranged from 0.5 to 5 wt.%. EXAFS data were analyzed within the multiple scattering formalism providing a detailed description of the atomic neighborhood in
