Abstract: An in-packaged multi-channel light engine is packaged for four or more sub-assemblies of optical-electrical sub-modules. Each is assembled with at least four laser chips, one or more driver chip, and one or more trans-impedance amplifier (TIA) chip separately flip-mounted on a silicon photonics interposer and is coupled to an optical interface block and an electrical interface block on a sub-module substrate. The in-packaged multi-channel light engine further includes a first frame fixture holding the four or more sub-assemblies and a second frame fixture configured to hold the first frame fixture with the four or more sub-assemblies. The in-packaged multi-channel light engine further includes an interposer plate inserted between the sub-module substrates and a module substrate and is compressed between a backplate member attached to a bottom side of the module substrate and a top plate member configured as a heatsink with a plurality of fin structures.

Abstract: An assembled electro-optical switch module includes a package substrate. Four optical socket members are disposed respectively to the package substrate. Each optical socket member includes four sockets closely packed in a row. Each socket has a recessed flat region with topside land grid array (LGA) interposer connected to bottom side solder bumps and a side notch opening aligned to an edge of the package substrate at the corresponding edge region. Sixteen optical modules in four sets are co-packaged in the package substrate. Each set has four optical modules respectively seated in the four sockets of each optical socket member with top side LGA interposer. Four clamp latch members are applied to clamp each of the four sets of optical modules in respective optical socket members. A data processor device with 51.2 Tbps data interface is disposed to the package substrate and electrically coupled to each of the sixteen optical modules.

Abstract: A co-packaged optical-electrical module includes a module substrate with a minimum lateral dimension no greater than 100 mm. The co-packaged optical-electrical module further includes a main die with a processor chip disposed at a central region of the module substrate, the processor chip being configured to operate with a digital-signal processing (DSP) interface for extra-short-reach data interconnect. Additionally, the co-packaged optical-electrical module includes a plurality of chiplet dies disposed densely along a peripheral region of the module substrate. Each chiplet die is configured to be self-packaged light engine on a sub-module substrate with a minimum lateral dimension to allow a maximum number of chiplet dies on the module substrate with a distance of any chiplet die from the main die smaller than 50 mm for extra-short-reach interconnect operation.

Abstract: An integrated compact light engine configured in a on-board in-package optics assembly. The compact light engine includes a single substrate to integrate multiple optical-electrical modules. Each optical-electrical module includes an integrated optical transceiver based on silicon-photonics platform, in which a transmit path configured to output four light signals centered at four CWDM wavelengths and from four laser devices and to modulate the four light signals respectively by four modulators driven by a driver chip and to deliver a multiplexed transmission light. A receive path includes a photodetector to detect four input signals demultiplexed from an incoming light and a trans-impedance amplifier chip to process electrical signals converted from the four input signals detected. A multi-channel light engine is formed by co-integrating or co-mounting a switch device with multiple compact light engines on a common substrate member to provide up to 51.2 Tbit/s total capacity of data communication with median-or-short-reach electrical interconnect.
