Abstract: “Hybrid photonic devices” describe devices wherein the optical portion—i.e., the optical mode, comprises both the silicon and III-V semiconductor regions, and thus the refractive index of the semiconductor materials and the refractive index of the bonding layer region directly effects the optical function of the device. Prior art devices utilize an optically compliant layer that is the same material as the III-V substrate; however, during the final sub-process of the bonding process, the substrates must be removed by acids. These acids can etch into the bonding layer, causing imperfections to propagate at the interface of the bonded material, adversely affecting the optical mode shape and propagation loss of the device.Embodiments of the invention utilize a semiconductor etch-selective bonding layer that is not affected by the final stages of the bonding process (e.g., substrate removal), and thus protects the bonding interface layer from being affected.

Abstract: A method for fabricating ion exchange waveguides, such as lithium niobate or lithium tantalate waveguides in optical modulators and other optical waveguide devices, utilizes pressurized annealing to further diffuse and limit exchange of the ions and includes ion exchanging the crystalline substrate with a source of ions and annealing the substrate by pressurizing a gas atmosphere containing the lithium niobate or lithium tantalate substrate above normal atmospheric pressure, heating the substrate to a temperature ranging from about 150 degrees Celsius to about 1000 degrees Celsius, maintaining pressure and temperature to effect greater ion diffusion and limit exchange, and cooling the structure to an ambient temperature at an appropriate ramp down rate. In another aspect of the invention a powder of the same chemical composition as the crystalline substrate is introduced into the anneal process chamber to limit the crystalline substrate from outgassing alkaline earth metal oxide during the anneal period. In yet another aspect of the invention an anneal container is provided that allows for crystalline substrates to be annealed in the presence of powder without contaminating the substrate with the powder during the anneal process. Waveguides manufactured in accordance with the method exhibit superior drift performance.
