Abstract
An apparatus and method for embedding a laser source on a semiconductor substrate and an optical interconnect to couple the laser source to internal components of the semiconductor substrate. An on-die waveguide is integrated on the semiconductor substrate. A package waveguide is disposed on the semiconductor substrate and evanescently coupled to the on-die waveguide. The laser source is embedded within the packaged waveguide to provide an optical signal to the on-die waveguide via the package waveguide.
