Method of manufacturing a compact optical semiconductor module capable of being readily assembled with a high precision
TL;DR: In this article, an optical semiconductor module is mounted on a substrate through a plurality of solder bumps each of which has a predetermined height and which is formed by molten solder, each of the bumps is surrounded by a side wall lower than the predetermined height of each bump.
Patent

Patent
Optical fiber connector having a glass ferrule covered by a thin reinforcing layer
Tetsuji Ueda,Yasuhisa Tanisawa +1 more
TL;DR: Optical fiber connector comprises a ferrule receiving an optical fiber and a sleeve member for holding the ferrule as mentioned in this paper, which is made of glass on which a thin layer is deposited for reinforcement of the body.
Patent
Optical device capable of reliably fixing a substrate to a package
TL;DR: In this paper, a block is made of a welding material and welded to a predetermined part on a wall surface of the package, which is then brought into contact with the second internal surface and the predetermined area.
