Optical interconnection apparatus and method

摘要

The present invention relates to the apparatus and method for optical interconnection. The present invention provides an optical interconnection structure comprising: a substrate on which double side perforated multi-hole through a predetermined region is formed; bottom hole which is etched and tapered for optical fiber array is bigger than upper hole which is etched for the optical devices. The present invention provides the optical interconnection structure that can facilitate the optical interconnection between the active optoelectronic devices that transmit/receive the optical signals and the optical fiber array, making it possible to align easily and acutely between the optical devices and optical fiber array.

1. An optical interconnection structure comprising:
a substrate having both sides, a plurality of perforated holes being formed through the substrate, optical devices being bonded to one side of the substrate, optical fibers being connected to the other side of the substrate, wherein each of the plurality of perforated holes includes a upper hole portion and a bottom hole portion and each optical device is placed on the upper hole portion, and each optical fiber is attached to the bottom hole portion, and wherein the bottom hole portion has tapered shape and the end of each optical fiber has a lens shape, the lens shape being formed by melting the end of the optical fiber and pulling outward the end of the optical fiber simultaneously with melting, wherein the bottom hole portion further includes a bottom surface of tapered shape with a different angle in the boundary between the upper hole portion and the bottom hole portion.
