    摘要： 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.

    摘要： The present disclosure relates generally to a fiber holder for holding optical fibers. The fiber holder can include a main holder body having a length that extends between first and second ends of the main holder body, a width that extends between first and second side walls of the main holder body, and a height that extends between top and bottom sides of the main holder body. The main holder body can define a plurality of fiber positioning grooves that extend along the length of the main holder body and spaced across the width of the main holder body. The main holder body also includes a fiber engagement structure having a fiber engagement surface. The fiber engagement structure can be aligned with an open region that interrupts the plurality of fiber positioning grooves. The fiber engagement structure can extend through the height of the main holder body from the top side to the fiber engagement surface.

    摘要： A multi-piece optical coupling device comprises a first piece that includes one or more first receiving elements configured to receive and secure one or more optical waveguides. The first piece further includes one or more light affecting elements configured to affect one or more characteristics of light from the optical waveguides while propagating the light within the optical coupling device. A second piece is separate from the first piece and includes one or more second receiving elements configured to receive the waveguides, the first receiving elements and the second receiving elements configured to align the second piece and the first piece using the optical waveguides. The second piece also includes one or more mating alignment features configured to engage with a mating optical coupling device and to align the optical coupling device with the mating optical coupling device.

    摘要： A ferrule has a receiving area for receiving and securing an optical waveguide and an optical element for receiving light from an optical waveguide received and secured at the receiving area and changing at least one of a divergence and a propagation direction of the received light. A plurality of registration features are configured to permit a stacking of the ferrule in a stacking direction such that the ferrules in the stack are aligned relative to each other along a length of the ferrule and along a direction perpendicular to the stacking direction.
