Original Abstract Submitted
A temperature control module () is mounted on the metal stem (). A support block () is provided on the temperature control module. A back surface of a dielectric substrate () is joined to a side surface of the support block. A differential driving signal line () is provided and a semiconductor light modulation device () is mounted on a principal surface of the dielectric substrate. A first lead pin () is connected to one end of the differential driving signal line. The other end of the differential driving signal line is wire-connected to the semiconductor light modulation device. The temperature control module is wire-connected to the second lead pin (). The dielectric substrate has a cutout () on a side of the metal stem. Parts of the temperature control module and the support block are positioned in an internal space of the cutout.
