Abstract
A method for internal laser welding of metallized optical components for attachment of optical fibers which comprises the steps of: milling a 'V' groove in one end face of a fiber carrier; aligning an optical fiber in the 'V' groove; polishing end faces of an integrated optics chip and the fiber carrier assembly; depositing chromium layers on integrated optics chip and the fiber carrier assembly; depositing eutectic alloy on chromium layers; optically aligning the optical fiber and a wave guide in the integrated optics chip; and applying a pulse laser beam for an internal laser weld between the end face of the integrated optics chip and the end face of the fiber carrier assembly.
