Metal coated optical fiber array module

Abstract

A metal coated optical fiber array module including a metal coated optical fiber array, an arranging substrate having arranging grooves for loading the optical fiber array, wherein a metal is coated on the upper surface including the arranging grooves and the optical fiber array loaded into the arranging grooves is united therewith through the medium of the metal, and a cover for protecting and fixing the optical fiber array loaded into the arranging grooves of the arranging substrate. It is preferable that the optical fiber array module further includes a planar substrate having holes into which the optical fiber array is to be inserted, wherein the optical fiber array loaded on the arranging substrate is inserted into the holes and united with the arranging substrate. After the optical fibers are loaded, the ends thereof are easily polished. When the optical fibers are attached to a waveguide device, the ends of the arrayed optical fibers are enlarged to increase an attachment strength at the contact surface. The axes of the optical fibers are prevented from being tilted, by ultraviolet (UV) irradiation upon loading the optical fibers. Also, when the optical waveguide device is attached to a multi-core optical fiber, a contact surface is widened, thus improving environmental characteristics and reliability of a device package upon connection of the optical fibers.
