Latest Patents

David Capewell holds a patent for an "Interface for a-Si waveguides and III/V waveguides." This patent describes a method of coupling a waveguide to a multi-layered active device structure on a substrate. The method involves forming a junction area by etching the active device structure to create a sloped etch profile relative to the substrate. It also includes aligning multiple layers of the multi-layered active device structure via an etch stop adjacent to the structure. The waveguide is then deposited over the etched active device structure, resulting in a sloped active-passive junction that minimizes residual interface reflection in the coupled device. Additionally, the patent outlines a method for removing at least one laser layer in a sloped junction region to form passive amorphous silicon waveguides.
