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 optical transceiver includes a silicon photonics substrate and multiple devices. The devices are configured to process optical signals propagating to and from the optical transceiver, and to perform at least one of an optical-to-electrical conversion of received optical signals to incoming electric signals and an electrical-to-optical conversion of outgoing electric signals to transmitted optical signals. The devices are each fabricated to include respectively a package substrate configured according to one of multiple different package substrate mounting technologies. Each package substrate among the multiple devices is mounted on the silicon photonics substrate according to mounting requirements of the respective package substrate mounting technology of that package substrate. At least two of the package substrates are mounted according to the mounting requirements of different package substrate mounting technologies.

Abstract: An integrated optical transceiver includes a transmitter unit and a receiver unit each provided on a surface region of a substrate member. The transmitter unit includes four laser devices configured to output four laser lights and a set of four power splitter devices coupled to the four laser lights to split each of the four laser lights to two replicated transmit paths. The receiver unit has two replicated receive paths each including a photodetector device and a transimpedance amplifier device coupled to the photodetector device. A planar light circuit block is mounted on the substrate member and includes a multiplexer device configured to couple the four laser lights of the transmitter unit and multiplex to one output light delivered to an optical output port and a demultiplexer device configured to receive an input light from an optical input port and demultiplex to four input optical signals for the receiver unit.

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.
