ABSTRACT:
A conventional optical fiber not coated with a metal layer is provided. A solder layer is filled into between a case, for an optical module wherein an optical element is optically coupled with the optical fiber within the case, and a cover conforming to the shape of the case, thereby simply conducting hermetical sealing. Thereafter, a resin, such as a silicone resin, is potted in the optical fiber introducing section. The two-layer hermetical sealing can realize a method for hermetically sealing an optical fiber introducing section which can maintain airtightness high enough to ensure long-term reliability of an optical module. This can facilitate the hermetical sealing of an optical device particularly in its optical fiber introducing section.
