摘要： A method of coupling a waveguide to a multi-layered active device structure on a substrate is described. The method includes forming a junction area by etching the active device structure to form a sloped etch profile with respect to the substrate, aligning multiple layers of the multi-layered active device structure via an etch stop adjacent the multi-layered active device structure, and depositing the waveguide over the etched active device structure, wherein a sloped active passive junction is formed at the junction area that reduces residual interface reflection in a resulting coupled device. Also described is a method for removing at least one laser layer in a sloped junction region forming passive amorphous silicon waveguides. This includes depositing a SiN layer for use as an etch mask, patterning a photoresist mask, patterning the SiN layer by reactive ion etching, stripping the photoresist mask, and etching the at least one laser layer.
