  • Patent number: 12259576
    Abstract: Depositing a side slab structure on a cladding layer before etching a supporting dielectric prevents tapering of a silicon waveguide during etching of the supporting dielectric and a substrate. For example, the side slab structure may be deposited over the silicon waveguide and the cladding layer after etching the cladding layer. As a result, when an electronic device is integrated ex situ on the substrate, wave intensity and/or total internal reflection is improved, which improves an efficiency of the electronic device.
