Abstract
A lead frame for mounting thereon an optical semiconductor device includes a stage, a plurality of leads arranged in a peripheral region of the stage and a support member extended from said stage. An optical semiconductor device includes such a lead frame, a substrate mounted on the stage of the lead frame, an optical semiconductor chip mounted on the substrate and having electrodes which are electrically connected to the electrodes. An optical fiber has a leading end which is mounted on the substrate and an intermediate portion which is fixedly secured to the support member so that the leading end portion is located at a predetermined position with respect to the chip. An insulating sealing material hermetically seals the optical semiconductor chip, the leading end portion of the optical fiber and at least a part of the support member.
