PACKAGE FOR HOUSING OPTICAL SEMICONDUCTOR ELEMENT

Japanese Patent JP3696737

B

PROBLEM TO BE SOLVED: To provide a package for housing an optical semiconductor element which makes the hermeticity of the package perfect and is capable of normally and stably operating the optical semiconductor element housed therein for a long period of time.
SOLUTION: This package includes a base body 1 which is erected with ceramic side walls 1b along three sides among the outer peripheries of a ceramic bottom plate 1a of an approximately square shape and a metallic side wall 1c along the remaining one side and a metallic member 8 for fixing the optical fiber which is mounted at the metallic side wall 1c of the base body 1 and is welded with mounting fittings 10 of the optical fiber 9. When the coefficient of thermal expansion of the ceramic bottom plate 1a and the ceramic side walls 1b is defined as (a), the coefficient of thermal expansion of the metallic side wall 1c as (b) and the coefficient of thermal expansion of the metallic member 8 for fixing the optical fiber as (c), these coefficients are a<b<c.
