摘要： A PD (20) is mounted to a position offset (23) as viewed in the direction orthogonal to the center of an optical axis (14) of backward light (13) of an LD (11) in such a manner that a light receiving plane (21) thereof becomes substantially parallel to the center of the optical axis. Alternatively, the PD (20) is mounted thereto so that the light receiving plane of the PD is inclined at angles ranging from about 0° to about 30° to the center of the optical axis of the backward light. Further, the PD whose side face on the LD side is inclined, is used to repeatedly reflect the backward light between the PD and an LD mounting substrate, after which the backward light is launched on the light receiving plane 21. An optical module equipped with a PD for monitoring optical output power of an LD can be applied even to a junction up LD which reduces the number of parts, reduces even the number of connections by solder or the like and the number of electrical connections by wire bonding or the like, and makes no use of a base for the PD. Thus, low-cost PD mounting can be realized.

摘要： The present invention is related to an optical communication module for transmitting high frequency signals (e.g., 10 Gbit/s and higher data rates) between an optical element and an external circuit. In an illustrative embodiment, the optical communication module includes signal transmission lines and ground lines formed on a ceramic substrate, a flexible wiring board, and a printed circuit board. The widths of the signal lines and the ground lines vary, as well as the spacing between the signal and ground lines. This facilitates characteristic impedance matching among the signal lines to within about 50Ω.

摘要： To provide a reliable optical pickup device, a pickup case and an optical component including a lens are fixed by laser welding to increase the welding strength and reduce the positional displacement due to environmental changes. In a laser welded portion between a pickup case and an optical component including a lens, the optical component is provided with a joint portion having a convex protrusion at a portion to be joined to the pickup case. Laser beam irradiation is performed extending longer than the protrusion to form a thick welded portion at an end of the protrusion, in order to increase welding strength between the optical component and the pickup case.
