Mounting of an integrated optic circuit on a motherboard for the connection of optic fibers to form a miniature optical component

A miniature optical component formed by the mounting of an integrated optic circuit chip has waveguides on a motherboard for connection with optic fibers. The fibers are positioned and aligned in parallel grooves hollowed out in the motherboard. The surface of the motherboard is hollowed out with female microstructures in the shape of axial buttonholes with sub-millimetrical dimensions, and the face of the chip has projecting male microstructures formed by metal deposition, capable of fitting into and sliding axially in the female microstructures during the mounting of the component. There is also provided a method for mounting a miniature component of this kind and a method for the matrix-based manufacture of a motherboard and a matrix device.
