  • Fibre support
    Publication number: 20030012508
    Abstract: A method for holding an end of at least one optic fibre in alignment for optical communication with an end of a respective optic element at a side edge of an optic chip; the method including the steps of: providing a fibre support supporting at least one optic fibre; assembling the fibre support and the optic chip so as to align the end of the at least one optic fibre with the end of the respective optic element at the side edge of the optic chip, wherein the fibre support includes a first portion that is configured to extend beyond the side edge over the optic chip when the end of the at least one optic fibre is aligned with the end of the respective optic element at the side edge; and then bonding said first portion of the fibre support to the optic chip to secure the fibre support to the optic chip.
