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： A semiconductor light-receiving device 1a comprises a first InP layer 12 having a first conductive type region 20a, a second InP layer 16 having a second conductive type, and an InGaAs light-receiving layer 14 disposed between these layers 12, 16. The InP layer 16 of second conductive type has a maximum carrier concentration of 1×1017 cm−3 or higher. Because of this carrier concentration, the depletion layer caused by an applied reverse bias to extend into the InP layer 16 becomes sufficiently small. Therefore, this depletion layer spreads within the light-receiving layer 14 in which electron-hole pairs are generated. Hence, the applied voltage can fully be utilized for drifting generated carriers. Thus provided is a semiconductor light-receiving device in which the occurrence of wave tails is reduced.
摘要翻译：半导体光接收装置1a包括具有第一导电类型区域20a的第一InP层12，具有第二导电类型的第二InP层16和设置在这些层12,16之间的InGaAs光接收层14。第二导电类型的层16具有1×10 17 cm -3以上的最大载流子浓度。由于这种载流子浓度，由施加的反向偏压引起的延伸到InP层16中的耗尽层变得足够小。因此，该耗尽层在产生电子 - 空穴对的光接收层14内扩散。因此，施加的电压可以完全用于漂移所产生的载体。因此，提供了一种减少波尾发生的半导体光接收装置。

摘要： A light absorbing layer, and a window layer formed thereon constitutes a first conduction-type semiconductor layer. In a part of this first conduction-type semiconductor layer there is provided a second conduction-type region extending to the light absorbing layer through the window layer. A part of the window layer around the second conduction region is selectively removed. Consequently even when light intended to enter a light detecting region is incident outside of the light detecting region, most of the carriers generated there are recombined at a surface level of the light absorbing layer before diffusing in a depletion layer. This light detecting device therefor does not substantially detect sensitivity to light incident outside the light detecting region.
