Abstract: A wafer-level optoelectronic packaging method includes fabricating a pre-singulated wafer. The pre-singulated wafer has a plurality of sub-mounts. A first sub-mount of the plurality of sub-mounts includes an optical waveguide formed on a substrate, a multi-layered sub-mount boundary wall that is formed on the optical waveguide, and a v-groove that is external to the sub-mount boundary wall. A plurality of optical dies are attached to the corresponding plurality of sub-mounts, such that each optical die is aligned to the optical waveguide of the corresponding sub-mount. A cap-wafer including a plurality of caps is attached to the pre-singulated wafer to obtain an encapsulated pre-singulated wafer. The encapsulated pre-singulated wafer is diced to obtain a plurality of optoelectronic packages. The optical waveguide of each optoelectronic package serves as an interconnection conduit between the corresponding optical die and an optical fiber placed in the corresponding v-groove.

Abstract: An optical interconnect system has a transmitter and a receiver connected by a single mode fiber. An array of DML lasers in the transmitter emits multiple wavelengths which are multiplexed to the single mode fiber with an array waveguide grating (AWG) device. The receiver demultiplexes the different wavelengths by an AWG polymer waveguide fabricated in a trench on the silicon surface. The AWG demultiplexer includes a high-NA polymer waveguide which has an end reflector approximately formed at 45 degrees for reflecting light from AWG into multiple photodetectors assembled outside the trench. Optionally, a number of through-silicon-vias (TSVs) allow electrical connection access to the lasers and the driver circuit from the backside of the silicon substrate by external power sources.
