New fields of application for amorphous silicon in integrated optics are developed. First, the influence of deposition method and process parameters on the material properties is investigated. The effects of thermal treatments are analyzed. Low-loss, monomode waveguides are fabricated. Then, a low-temperature PECVD process is used to realize a three-dimensional taper concept with shadow masks. The feasibility to stack waveguides application of a planarization process is studied, and vertical coupling between waveguides is simulated in order to estimate process specifications. Furthermore, waveguides with horizontal slots are fabricated.Neue Anwendungsgebiete für amorphes Silizium in der integrierten Optik werden entwickelt. Zunächst wird d...
