The combination of hybrid nanowire photodetector on silicon photonic crystals has the potential to be both highly sensitive and ultrafast. A p-i-n nanowire was integrated into a silicon photonic crystal via nanomanipulation technique and has been successfully implemented as a photodiode on silicon chip with Al:ZnO transparent electrode. The hybrid nanowire photodiode can detect laser light through the Al:ZnO coated input waveguide and is capable of measuring the photonic crystal enhanced photocurrent. In addition, a measurement of the enhanced photocurrent in the light cone by the nanoantenna was also conducted. Our results reveal the prospects for future photonic on-chip processors utilizing CMOS-compatible hybrid nanowire photodetector in a photonic crystal.

集成在硅光子晶体中的混合纳米线光电探测器

硅光子晶体上混合纳米线光电探测器的组合具有很高的灵敏度和超快的潜力。针状纳米线通过纳米处理技术集成到硅光子晶体中，并已成功实现为带有Al：ZnO透明电极的硅芯片上的光电二极管。混合纳米线光电二极管可以检测通过涂有Al：ZnO的输入波导的激光，并且能够测量光子晶体增强的光电流。此外，还进行了纳米天线对光锥中增强的光电流的测量。我们的结果揭示了在光子晶体中使用CMOS兼容混合纳米线光电探测器的未来光子片上处理器的前景。
