A semiconductor device for optically coupling a semiconductor light-emitting device to an optical fiber, includes (a) a lens (11) which focuses lights emitted from the semiconductor light-emitting device, onto the optical fiber, (b) a shell (12) which supports the lens (11) therewith, the shell (12) being comprised of a cylindrical first portion (12a), a second portion (12b) integral with the first portion (12a) at an upper end of the first portion (21a) and being formed centrally with an opening (12d) into which the lens (11) is to be fit, and a cylindrical third portion (12c) extending from the first portion (12a) upwardly beyond the second portion (12b), (c) glass (13) arranged around the lens (11) for keeping the lens (11) and the opening (12d) hermetically sealed, and (d) a reinforcement (14a, 14b) formed on upper and lower surfaces of the second portion (12b) for preventing the shell (12) from being deformed due to a stress acting on the shell (12). <IMAGE> |
