We demonstrated a novel silicon photonic platform constituting a D-shaped silicon cored fiber (SCF) for Schottky photodetector (PD). By using a handheld polishing machine, D-shaped SCFs can be fabricated in a fast and simple way. D-shaped SCFs offer stable platforms for traditional semiconductor processing and we show that Schottky PDs could be easily made on the fibers. Experiment results confirm an improved responsivity of 0.577 mA/W and the modulation bandwidth could reach 170 MHz. The D-shaped SCFs may open a new approach of making all-in-fiber silicon photonic devices.

D形硅芯光纤作为构建串联肖特基光电探测器的平台

我们演示了一种新颖的硅光子平台，该平台构成了用于肖特基光电探测器（PD）的D形硅芯光纤（SCF）。通过使用手持式抛光机，可以快速简便地制造D形SCF。D形SCF为传统的半导体加工提供了稳定的平台，并且我们证明了肖特基PD可以很容易地在光纤上制造。实验结果证实，响应度提高了0.577 mA / W，调制带宽可以达到170 MHz。D形SCF可能会开创一种制造全光纤硅光子器件的新方法。
