    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

    摘要: The invention provides a method for manufacturing a optical subassembly even when the assembly involves the positional deviation of the components that induces the discrepancy in the direction of the optical output beam from the optical device. The method first determines the position (x1, y1, z1) of the stub where the optical coupling between the stub and the optical device becomes the maximum. Next, the direction of the optical output beam from the optical device is calculated based on the position above, and, finally, the inclined direction of the end surface of the stub is aligned with the direction of the optical output beam evaluated in the previous step.

    摘要: In a planar optical waveguide type optical circuit 1, a reflection filter 4 is installed on the inside of a inclined groove 3, which is formed so as to cross optical waveguides 2n. Reflected light from the reflection filter 4 is detected by photodetectors 61n of a photodetector array 60, thereby the optical intensity of the signal light is monitored. As for the photodetectors 61n, there is adopted a constitution such that a sub-mounting substrate 70 is disposed at the top side of the optical circuit 1 to hold the photodetector array 60 with a photodetector mounting face 71, which is inclined at an angle α (0°

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.
