Abstract
A metallic ring is located on a multilayer ceramic substrate. An optical semiconductor laser is located on the multilayer ceramic substrate, inside the metallic ring. A metallic cap with a window is joined to the metallic ring. The metallic cap covers the optical semiconductor laser. An external heat sink is joined to an external side surface of the metallic cap. These features make it possible to improve high-frequency characteristics, producibility, and heat dissipation.
