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