Abstract: A transceiver module for providing operational resilience is presented. The transceiver module is configured to receive first data via a first optical module in a first configuration of operation and detect, using an adapter that is operationally connected to the first optical module, an operational failure of the first optical module. In response to detecting the operational failure, the transceiver module is configured to switch, via the adapter, from the first configuration of operation to a second configuration of operation by: automatically engaging a second optical module; triggering the first data that was initially directed into a first input port of the first optical module to be directed into a second input port of the second optical module; and receiving the first data from a second output port of the second optical module.

Abstract: Apparatuses, systems, and associated methods of manufacturing are described that provide an optical interposer and associated communication system. An example optical interposer includes a substrate having a first end that receives a first optical fiber welded thereto and a second end that receives a plurality of photonic integrated circuits (PICs) attached thereto. The interposer further includes an optical waveguide network defined by the substrate that provides optical communication between the first welded optical fiber and the plurality of PICs. The optical waveguide network also includes optical redistribution elements supported by the substrate. In an operational configuration, the optical interposer receives a first input optical signal from the first welded optical fiber, and the plurality of optical redistribution elements successively split the first input optical signal such that a plurality of output optical signals is directed to the plurality of PICs.

Abstract: An optical coupler and method of assembly are described that provide efficient coupling from the photonic integrated circuit (PIC) waveguide layer to external components, such as optical fibers, VCSELs, photodetectors, and gain blocks, among others. The optical coupler includes a PIC that can be supported by a printed circuit board, an optoelectronic transducer supported by the PIC that can convert between optical signals and corresponding electrical signals, and a coupled waveguide assembly. The coupled waveguide assembly includes a low-index waveguide, a high-index waveguide, and a reflective surface that changes a pathway of the optical signals to direct the optical signals from the optoelectronic transducer into the low-index waveguide or from the low-index waveguide into the optoelectronic transducer.
