Black phosphorus (BP) promises high‐performance humidity sensing, due to its unique electrical, mechanical, and surface properties. Different from traditional transistor‐based BP humidity sensors, herein, an all‐fiber sensing strategy is proposed by integrating BP nanosheets with etched single‐mode fiber (ESMF). The experiments show that transmitted light in the ESMF can be effectively modulated by the coated BP nanosheets as relative humidity varies from 35% to 80%. Due to the combination of unique sensing characteristics of BP materials with a high sensitivity of optical modulation strategy, highly responsive humidity sensing is achieved with the response time as fast as 7 ms. This work demonstrates a BP‐based all‐optical sensing platform not only for high‐performance humidity sensing, but also for opening up new opportunities for many potential vapor/gas sensing applications in the fields of biomedicine and chemistry.

“…Black phosphorus [ 88 ] is another significant member of 2D materials (see Figure 1c), which owns a large operation range from VIS to MIR regions, bridging the wavelength gap between graphene and TMDCs. [ 89 ] Precisely, the bandgap of BP exhibits a linear increment as the number of layers decreases, which changes from 0.3 eV in bulk to 2 eV in monolayer, attributed to the electronic confinement in the vertical direction of 2D film. [ 90 ] Additionally, its bandgap can be further adjusted via chemical [ 91 ] or electrical engineering.…”

Silicon (Si) photonics have established as leading technologies in addressing the rapidly increasing demands of huge data transfer in optical communication systems with compact footprints, small power consumption, and ultradense bandwidth, which are driven by the next generation supercomputers and big data era. Particularly, Si photonics will penetrate into optical communication links at an ever-small scale, namely chip-to-chip and on-chip. However, the nanostructures made of Si with an indirect bandgap are not ideal candidates for on-chip light sources, modulators, and photodetectors, which most-frequently require optical materials with direct bandgap. Thanks to the advent of graphene, transition metal dichalcogenides and other two-dimensional (2D) materials, which can facilitate extraordinary progresses in improving device performance at the ultrathin scale, their integration with Si photonics furnishes a heterogeneous platform to construct fully functional and highly integrated photonic communication systems. In this work, the current advancements in the on-chip applications of Si photonics-2D materials heterostructures, inclusive of all essential chip-scale modules and integrated circuits, as well as the future prospective and challenges are reviewed and discussed. The present study sets out to objectively measure the feasibility of the hybrid integration between Si photonics and 2D materials in on-chip optical communications and the advanced applications beyond.

“…Their extremely tunable bandgap covering infrared up to visible frequencies [ 52 ] ( Figure a), highly anisotropic electronic dispersion, [ 117 ] optical properties [ 118 ] (Figure 1b,c), and optimal surface‐to‐volume ratio render BPNSs a promising material for several electronic and optoelectronic devices, such as transistors, gas sensors, and photodetectors. [ 119 ] The in‐plane anisotropy of BPNSs provides new opportunities for novel electronic, photonic, and thermoelectric devices. The high (anisotropic) carrier mobilities and large on/off ratios at room temperature make BPNSs an excellent material for transistors, superior to graphene, which has a poor on/off ratio, and TMDs, which have low mobilities.…”

Assembling different kinds of 2D nanosheets into heterostructures presents a promising way of designing novel artificial materials with new and improved functionalities by combining the unique properties of each component. In the past few years, black phosphorus nanosheets (BPNSs) have been recognized as a highly feasible 2D material with outstanding electronic properties, a tunable bandgap, and strong in‐plane anisotropy, highlighting their suitability as a material for constructing heterostructures. In this study, recent progress in the construction of BPNS‐based heterostructures ranging from 2D hybrid structures to 3D networks is discussed, emphasizing the different types of interactions (covalent or noncovalent) between individual layers. The preparation methods, optical and electronic properties, and various applications of these heterostructures—including electronic and optoelectronic devices, energy storage devices, photocatalysis and electrocatalysis, and biological applications—are discussed. Finally, critical challenges and prospective research aspects in BPNS‐based heterostructures are also highlighted.
