Package for housing optical semiconductor element



PROBLEM TO BE SOLVED: To provide a package for housing an optical semiconductor element for allowing an optical fiber to satisfactorily receive a light excited by an optical semiconductor element through a cylindrical lens member, and allowing the optical semiconductor element housed inside to normally and stably operate in a long period. SOLUTION: This is a package for housing an optical semiconductor element constituted of a substrate 1 having a loading part 1a of an optical semiconductor element 4, frame body 2 attached to the substrate 1 and provided with a through-hole 2a at the side part, cylindrical metallic fixing member 9 inserted and fixed into the through-hole 2a, whose outside end part an optical fiber 11 is inserted and fixed into, cylindrical lens member 10 inserted and fixed inside the metallic fixing member 9, and cover body 3 mounted on the upper face of the frame body 2. Only the outer peripheral face of the central part of the cylindrical lens member 10 is fixed through brazing filler metal to the inner peripheral face of the metallic fixing member 9, and the metallic fixing member 9 is fixed with an interval with the inner peripheral face of the through- hole 2a. Thus, any stress can not be concentrated on the cylindrical lens member 10, and any crack can not be generated.
