Abstract

PURPOSE:To enable fixing a columnar lens into a groove formed to an upper surface of a heat sink stably by a method wherein the columnar lens is held between the groove formed to the upper surface of the heat sink and a groove of another columnar lens holder, and both are bonded and fixed at sections except the grooves. CONSTITUTION:A heat sink 10 is prepared which is formed by making up a V- groove 11 and a notch 12 onto a surface of an Si monocrystal and evaporating an Sn film 13 on the surface having the groove 11, and a fiber lens 1 manufactured as a columnar lens is previously placed along the groove 11. A columnar lens holder 30 is prepared which is formed by making up a V-groove 31, a notch 32 and an Sn film to another Si monocrystal according to the same treatment, and the holder is placed on the heat sink 10, stacking the groove 31 on the lens 1. The whole is heated under this condition, and cooled, thus bonding the heat sink 10 and sections except the grooves 11, 31 of the holder 30, then fixing the lens 1. In this case, a semiconductor laser diode 50 can be fixed under a condition that is brought very close to the lens 1 by placing the diode 50 on the heat sink 10 and simultaneously melting and fixing the diode.
