Carbon-based nanomaterials such as carbon nanotubes (CNTs) and graphene have great potential for high-performance all-carbon photodetectors due to their unique optical and electronic properties. Here, we assemble a hybrid CNT/graphene film prepared by depositing CNTs on a single layer graphene with a side-polished optical fiber to achieve a novel all-fiber integrated photodetector. Because CNTs strongly enhanced the interaction between graphene and the fiber mode, the photodetector shows an extra-high photoresponsivity over the visible and infrared region. Especially at 1550 nm, the photoresponsivity is found to be ∼1.48 × 105 A W−1, which is 6.5 times larger than those of photodetectors without CNTs. These findings provide a highly versatile, reproducible, and low-cost platform to integrate novel zero-, one-, and two-dimensional materials into optical fibers and deliver more sophisticated functionalities.

具有CNT增强响应度的宽带全纤维集成石墨烯光电探测器。
诸如碳纳米管（CNTs）和石墨烯之类的基于碳的纳米材料由于其独特的光学和电子特性，对于高性能全碳光电探测器具有巨大的潜力。在这里，我们组装了通过将碳纳米管沉积在单层石墨烯上并通过侧面抛光的光纤制备的碳纳米管/石墨烯混合薄膜，从而实现了一种新型的全光纤集成光电探测器。由于CNT极大地增强了石墨烯和纤维模之间的相互作用，因此光电探测器在可见光和红外区域显示出超高的光响应性。尤其是在1550 nm处，发现光响应率为〜1.48×10 5 AW -1，是没有CNT的光电探测器的6.5倍。这些发现为将新型零维，一维和二维材料集成到光纤中并提供更复杂的功能提供了一个高度通用，可复制且低成本的平台。
