ABSTRACT:
The present invention relates to an optical device capable of operating at high speeds. This optical device includes an optical fiber, an optical semiconductor element, a base member, a signal terminal, and a pair of ground pins. The optical fiber is optically connected to the optical semiconductor element. The base member is formed of a conductor and has a first surface and a second surface. The optical semiconductor element is mounted on the first surface. The first surface and the second surface are substantially parallel to each other, for example. The signal terminal is electrically connected to the optical semiconductor element. The signal terminal is inserted through a hole extending from the first surface to the second surface of the base member and fixed in the hole filled with a glass paste so that a predetermined characteristic impedance is obtained between the signal terminal and the base member. The pair of ground pins are fixed to the second surface of the base member on the opposite sides of the signal terminal. With this configuration, characteristic impedance matching can be facilitated, and grounding can be enhanced, thereby allowing high-speed operation of the optical device.
