Application: Multi-fiber interface apparatus for photonic integrated circuit (Patent ID: US20230418004A1)
The patent filed by Corning Inc. describes multi-fiber interface apparatuses designed to facilitate optical coupling between optical fibers and a photonic integrated circuit (PIC). The apparatus includes an optically transmissive substrate with a recess for mounting the PIC, a fiber array coupling member with optical elements to promote coupling, and passive alignment features for precise alignment. The design allows for relaxed fiber alignment tolerances, simplified fabrication, and integration with printed circuit boards (PCBs).
The apparatus consists of various components such as second mirrors, focusing lenses, and first mirrors to reflect and direct optical beams between the optical fibers and the PIC. The optically transmissive substrate can have electrically conductive vias for enhanced functionality. Additionally, the apparatus can be mounted on a printed circuit board, with the PIC arranged within a recess defined in the substrate. The use of passive alignment features ensures accurate alignment between the optical fibers and the PIC, ultimately improving optical coupling efficiency. Overall, the design offers a practical solution for achieving optical coupling in a multi-fiber interface setup with simplified fabrication and integration capabilities.
