Polymer Optical Fiber Array and Package Structure for Planar Optical Circuit Device Connection

摘要

Disclosed are a polymer optical fiber array and a polymer package structure useful for low-cost, high-reliability connection technology of multi-channel planar optical circuit devices, which are expected to be increased in the future for the transfer of a large amount of information required in an information society. The present invention uses an optical fiber array molded of a polymer material as a component for connecting multiple optical fibers for low cost and high reliability of a planar optical circuit device. The optical fiber array can be made at once by molding, and the holes in which the optical fiber is located can be formed with high precision during molding. When the optical fiber array is formed of polymer resin, the end of the optical fiber does not require many components for fixing, and the level of ultra precision processing technique required is low, and is suitable for mass production. The optical fiber array is made of a polymer composite material made of fused silica filled with a thermosetting epoxy resin in consideration of mechanical strength and dimensional stability, and a snap joint using an elastic body for simple and reliable connection of planar optical circuit devices. ) Use a coupling structure.
