    摘要: A method is described for producing stacked optical waveguides in a silicon dioxide substrate and includes the steps of: etching a first trench in the substrate; filling the first trench with a glassy optical transmission media; depositing a layer of silicon dioxide over the filled trench; etching a second trench in the silicon dioxide layer, the second trench aligned with the first trench; and filling the second trench with a glassy optical transmission media.
