摘要： The present invention provides an optical module in which the level of the lead frame coincides with the optical axis of the fiber. The module 1 comprises a container 4, a subassembly 2, a base member 5 and a lead frame 6. The subassembly 2 includes a substrate, on which the semiconductor optical device and the optical fiber are mounted. The container 4 has a pair of surface. One surface is securing the lead frame thereon while the base member is attached to the other surface of the container 4. The base member comprises an island portion and a frame portion. The subassembly 2 is placed on the island and the frame portion is fixed to the container 4. Island support portions connecting the island portion to the frame portion is deformed in the molding process, thus aligning the subassembly 2.

摘要： A bi-direction optical module with an arrangement to reduce the crosstalk noise is disclosed. The optical module comprises a laser diode (LD) driven by a differential signal and a photodiode (PD) on a single package. The PD is mounted on a position where the electrical potential measured from respective interconnections connected to the anode and to the cathode of the LD becomes the midpoint of the interconnections. The capacitances with respect the stem, where the LD and the PD are mounted thereon, viewed from the anode and the cathode of the LD becomes substantially equal to each other, or distances from the PD to respective interconnections are adjusted depending on the length of the interconnection facing the PD. Twisting the interconnections to the LD may be effective to reduce the crosstalk.
