摘要： The present invention provides a receiving optical subassembly (ROSA) with a co-axial shape and a stem for mounting semiconductor devices thereon that improves the high frequency performance of the ROSA. The ROSA mounts a photodiode (PD) and a pre-amplifier on a stem and the stem has a hollow the PD and the pre-amplifier are mounted therein. Since the hollow has a depth substantially equal to a thickness of the pre-amplifier, the bonding wire from the pre-amplifier to the surface of the stem may become shortest to reduce the parasitic inductance of the bonding wire and to enhance the high frequency performance of the ROSA.
摘要翻译：本发明提供一种具有同轴形状的接收光学子组件（ROSA）和用于在其上安装半导体器件的杆，其改善了ROSA的高频性能。 ROSA在杆上安装光电二极管（PD）和前置放大器，并且杆具有中空的PD，并且前置放大器安装在其中。由于中空部的深度基本上等于前置放大器的厚度，所以从前置放大器到杆的表面的接合线可能变得最短以减小接合线的寄生电感并提高高频性能的ROSA。

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°
