Abstract
A sealed airtight container wherein the width of the exposed electrode part provided in a ceramic terminal part is enlarged, and the exposed electrode part is connected to a wiring part and the width of the wiring part is equal to the enlarged width of the electrode part. A sealed airtight container for an optical-semiconductor with a small heat generation in the metallized wiring layer, small power consumption and large current carrying capacity, and an optical-semiconductor module with a stable optical output can be obtained.
Claims13
A sealed optical-semiconductor housing comprising a bottom plate for mounting an optical-semiconductor element thereon, a side-frame, and a sealing cover, the side-frame having means for supporting a ceramic terminal part and means for fixing an optical fiber, and a plurality of electrodes having an outer exposed electrode part, a hidden electrode part covered by a ceramic layer of said ceramic terminal part, and an inner exposed electrode part, wherein, for at least one of said electrodes, a portion of the hidden electrode part is formed as an enlarged portion having a width greater than a width of the outer exposed electrode part, and wherein the outer exposed electrode part of said at least one of said electrodes is connected to an external lead wire.
