In the past few years of research, the fusion of silica fibers with 2D materials has facilitated the rapid development of in-line manipulation of light beams in terms of polarization, phase, intensity, and frequency, which has led to the integration of all-fiber photonics and optoelectronics. But most applications are still in the proof-of-concept or prototype stage, and many key challenges, such as batch replication and reliable packaging of devices, remain to be solved for eventual practical applications. With advanced fiber manufacturing, there are sophisticated techniques to fabricate various bulk fiber structures, such as cutting fiber sides. Recently developed functional inks and prints of 2D materials are being used in efficient, low-cost mass production and may provide the ultimate solution for most hybrid fiber-optic devices. Device encapsulation is another important issue to achieve long-term stable operation of 2D materials, especially for gas-impermeable materials such as BP and MoTe 2 . Excellent electrical insulation, high thermal stability and chemical inertness make hexagonal boron nitride one of the most important candidates for passivation and protective layers.
