An all‐in‐fiber broadband photodetector is realized by integrating a micrometer‐scale multilayer graphene‐MoS 2 ‐WS 2 van der Waals heterostructure film onto a fiber facet. The device detects visible and infrared with high sensitivity and fast response. As Yi‐Feng Xiong, Yan‐Qing Lu, Fei Xu, and co‐workers report in article 1800562 , the device generates photocurrent through competing photoconductive and photo‐bolometric effects. Broadband and gating‐free photodetectors and other novel optoelectronic devices could be developed from these findings.
