On-chip light sources are a critical part for an integrated Si photonic technology, yet they lag other photonic components in their level of development. In this chapter, Er used as an optical dopant and utilizing its intra-4f transition at 1.54µm w

We report on fabricating Er x Y 2-x SiO 5 nanocrystals using ErCl 3 •6H 2 O and YCl 3 •6H 2 O solutions and Si nanowires grown by VSL method. Use of crystalline host allows incorporation of up to 25 at % Er without clustering and loss of optical

Ridge-type ErxY2-xSiO5 waveguides were fabricated. Amorphous ErxY2-xSiO5 was deposited using reactive ion beam sputter deposition, and crystallized by high-temperature annealing. The inversion level achieved was 0.4, limited by grain-boundary scatter

Concentration controlled, nanocrystalline Er doped Y2SiO5 particles were fabricated. Using 2-level model the cooperative upconversion coefficient was determined. We find that Er-doped YSO has much lower cooperative upconversion than silica, enabling

Self-organized Si-Er heterostructure nanowires showed promising 1.54 microm Er(3+) optical activity. Si nanowires of about 120-nm diameter were grown vertically on Si substrates by the vapor-liquid-solid mechanism in an Si-Er-Cl-H(2) system using an

Optical activation of Si nanowires (Si-NWs) using sol-gel derived Er-doped silica is investigated. Si-NWs of about 100 nm diameter were grown on Si substrates by the vapor-liquid-solid method using Au catalysts and H2 diluted SiCl4. Afterwards, Er-do

Single-phase, polycrystalline Er(x)Y(2-x)SiO(5) thin films were deposited by reactive ion-beam sputter deposition and rapid thermal annealing. Due to the crystalline nature, the silicate thin films provide peak Er(3+) emission cross-section of 0.9 +/
