    • An apparatus which aligns a fiber core to a detector on an integrated circuit has a transmission material connecting them which steers the light provided through the fiber core to the detector even in the case of misalignment. The transmission material chosen has a characteristic of being able to have the spatial distribution of its index of refraction altered by electrical means. In this case, an electric field is applied in the area surrounding the path from the fiber core to the detector. Thus, even if the fiber core is not aligned to the detector, the light will be directed from the fiber core to the detector due to the path being surrounded by a lower index of refraction than the path itself. Thus, there is very little loss due to misalignment between the fiber core and the detector.
    • 将纤维芯与集成电路上的检测器对准的装置具有将它们连接的传输材料,即使在未对准的情况下也将通过纤维芯提供的光转向检测器。 所选择的透射材料具有能够通过电气方式改变其折射率的空间分布的特征。 在这种情况下,在从光纤芯到检测器的路径周围的区域中施加电场。 因此,即使光纤芯不与检测器对准,由于路径被路径自身折射率较低的折射线包围,所以光将从光纤芯线引导到检测器。 因此,由于纤维芯和检测器之间的未对准,损失非常小。
