Er<sup>3+</sup> excited state absorption and the low fraction of nanocluster-excitable Er<sup>3+</sup> in SiO<sub>x</sub>
Silicon nanoclusters (Si-nc) can be efficient sensitisers of surrounding Er ions, making Er-doped silicon-rich silica material very appealing for 1.5µm amplifiers and lasers pumped by broadband sources. Recent reports of optical signal enhancement in waveguides based in this system have increased th...
