Abstract

Methods and systems for a chip-on-wafer-on-substrate assembly are disclosed and may include in an optical communication system comprising an electronics die and a substrate. The electronics die is bonded to a first surface of a photonic interposer and the substrate is coupled to a second surface of the photonic interposer opposite to the first surface. An optical fiber and a light source assembly are coupled to the second surface of the interposer in one or more cavities formed in the substrate. A continuous wave (CW) optical signal may be received in the photonic interposer from the light source assembly, and a modulated optical signal may be communicated between the optical fiber and photonic interposer. The received CW optical signal may be coupled to an optical waveguide in the photonic interposer using a grating coupler.
