Optical interconnects are considered an essential addition to the silicon electronics platform.

This thesis investigates the sensitization of group IV doped silica films emitting at 1.535&#956;m for applications as silicon compatible light sources. Thin erbium-doped silica films containing excess silicon and germanium were deposited using a multi-gun sputter system. The composition of the deposited materials was verified by Rutherford Backscattering Spectrometry. Samples from each deposition were annealed in a controlled atmosphere tube furnace at temperatures between 500&ordm;C and 1100&ordm;C for 30 minutes. The photoluminescence spectra from the visible to the near-infrared region were acquired while pumping either near or far from the Er3+ absorption lines. Under both excitation conditions all samples annealed at temperatures below 1000&ordm;C show clear emission at 1.535&#956;m from Er3+ ions in the host material. In the current literature this is attributed to exciton mediated excitation of the Er3+. By contrast, in these studies indirect excitation was observed for samples annealed at temperatures well below the onset of nanocrystal nucleation and growth (between 500&ordm;C and 1000&ordm;C), suggesting excitation via small clusters or lattice defects. These findings could have significant implications in the further development of group IV sensitized silicon compatible gain media.","abstract_html":"The continued size reduction in electronic integrated circuits has lead to a demand for on-chip high-bandwidth and low loss communication channels.
