    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: An optical module with an arrangement is disclosed in which the module has the LD, the TEC, and the lens with the lens carrier also mounted on the TEC. The signal light from the LD is concentrated by the lens and reflected by the mirror each assembled with the lens carrier mounted on the TEC. The TEC is mounted on the bottom metal that covers the bottom of the ceramic package, the first layer of which is widely cut to set the TEC therein. The FPC is coupled in at least two edges of the first ceramic layer left from the cut.

    摘要: WDMs have been used to separate a plurality of signals spatially by the difference of wavelengths in prior bidirectional multiwavelength optical communication network. For excluding WDMs, linear PD/LD modules adopt eigen-wavelength photodiodes sensing only the light of an eigen wavelength but allowing all the wavelengths longer than the eigen wavelength. An n-member PD/LD module aligns (n-1) eigen wavelength photodiodes, PD1, PD2, PD3, . . . , PDn-1 of .lambda.1, .lambda.2, .lambda.3, . . . ,.lambda.n-1 and an LD of .lambda. n which satisfy inequalities .lambda.1
