摘要
A method includes defining a first waveguide in a first region of an optical device over a first dielectric layer over a silicon on insulator (SOI) substrate of the optical device and disposing a second dielectric layer on the first waveguide and the first dielectric layer of the optical device. The method also includes defining a second region on the second dielectric layer, the first dielectric layer, and the SOI substrate. The second region includes an integrated trench structure defined in the SOI substrate. The method further includes etching the second region to form an etched second region, disposing a third dielectric layer in the etched second region, and disposing a second waveguide on at least the third dielectric layer. The second waveguide is disposed to provide an optical coupling between the second waveguide and the first waveguide.
