PURPOSE:To make the element suitable to mass production by putting a light emission or reception element in a package, by inserting a light transmission guide, which has a focusing medium in its tip end, into the package on making it opposite to the light emitting or receiving part and by requiring no splice. CONSTITUTION:The semiconductor light emission or reception element 1 is put in the package 5, the light transmission guide 4, the tip end of which is provided with the focusing medium 7 that is to be opposite to the light emitting or receiving part 2, is put through the package 5. In this case, the guide 4 is made of hard glass tube, the spherical glass lens 7 is attached to the tip of the tube with adhesive 8, the optical fiber 3 is inserted into the guide 4 and its tip end is made contact with the lens 7. After this, the free end of the projected optical fiber 3 is secured with the jacket 9 of the fixed bed 10. In this way, the manufacturing means can be standardized and the manufacture can remarkably be eased. |
