Laser integration into a silicon photonics platform

Abstract:

The present disclosure provides for laser integration into photonic platforms in which a first wafer, including a first substrate and a first insulator that includes a first plurality of dies that each include a first set of optical waveguides, is bonded to a second wafer, including a second substrate and a second insulator that includes a second plurality of dies that each include a second set of optical waveguides. The bond between the two wafers defines a wafer bond interface joining the first insulator with the second insulator and vertically aligning the first plurality of dies with the second plurality of dies such that respective first sets of optical waveguides are optically coupled with respective second sets of optical waveguides.
