ABSTRACT:
An optical semiconductor module includes a substrate including a first plate member having strip lines for high-frequency signal transmission, located on a surface of the substrate and a second plate member including a feeding line on a surface, the first plate member having a loss angle at high frequencies smaller than that of the second plate member, and the second plate member including a material with a higher heat conductivity than that of the first plate member. The optical semiconductor module includes an integrated semiconductor laser and modulator including a modulator region having surface electrodes on a surface, and a laser region having a surface electrode on a surface, with an optical axis extending along the optical axis of the modulator region. The integrated semiconductor laser and modulator are located on the substrate such that the surface electrodes of the modulator region are bonded to the strip lines and the surface electrode of the laser region is bonded to the feeding line.
