Claim Text:
1. A semiconductor device comprising: a silicon substrate having a front side and a back side and defining a recess extending through the silicon substrate from the back side of the silicon substrate to the front side of the silicon substrate; a dielectric layer of first dielectric material, having a first refractive index, disposed on the front side of the silicon substrate, the dielectric layer defining a trench open to the recess defined by the silicon substrate; an optical waveguide comprising a second dielectric material, having a second refractive index greater than the first refractive index, disposed within the trench; a first electronic device formed in the silicon substrate on a first side of the recess; and a second electronic device formed in the silicon substrate on a second side of the recess, wherein the optical waveguide defines an optical path between the first electronic device and the second electronic device, wherein the dielectric layer extends at least partially between the first electronic device and the second electronic device, and the optical waveguide extends at least partially along a plane containing the first electronic device and the second electronic device.
