“…The shaping of glasses at microscale dimensions has been a matter of utmost importance for technological advancement. Eventually, control over morphology has paved the way for optical microresonators in various distinct shapes such as spheres, bottles, cylinders, loops, toroids, disks, and rings [2][3][4][5]. Every different resonator shape has its own pros and cons regarding the easiness of production, the highest achievable quality factor, the integrability, and the tunability.…”

Production of chalcogenide (As 2 Se 3 ) microresonators in sphere, loop, and bottle morphologies by the shaping of glasses at appropriate temperatures between cleaved silica tapers is reported. The quality factors exceed Q S 6.2× 10 5 , Q B 6.7 × 10 5 , and Q L 1.6 × 10 4 for the sphere, bottle, and loop microresonators, respectively. All-optical thermally assisted tuning with a rate of 0.61 nm/mW is demonstrated for a bottle microcavity pumped via a silica taper at a wavelength of 670 nm. This technique enables practical and robust in situ production of chalcogenide microresonators thermally spliced to silica fibers in several morphologies with a wide tuning range of size.

All-optical devices have become a research hotspot with the development of all-optical networks. [1,2] In recent years, a large number of all-optical devices based on 2D materials have been intensively investigated, [3][4][5][6][7][8][9] such as saturated absorbers (SAs), all-optical thresholders, optical Kerr switches, wavelength convertersand modulators. In 2015, an all-fiber all-optical modulator via the thermo-optic effect of graphene-deposited microfiber was demonstrated, [10] which set off a new wave of research in all-optical modulators based on the photothermal effect of 2D materials. After that, tungsten disulfide (WS 2 ), [11] black phosphorus, [12] MXene, [13,14] bismuthene, [15] and antimonene [16] have also been employed to devise all-optical modulators on platforms of Mach-Zehnder interferometer (MZI) and Michelson interferometer (MI). However, both MZI and MI structures are very sensitive to ambient temperature and stress perturbations, leading to poor environmental stability. [17,18] Additionally, the response time of the all-optical modulators based on the photothermal effect of 2D materials is several milliseconds, severely limiting their practical applications. Therefore, it is of great importance to improve the response speed and environmental stability of the all-fiber all-optical modulators.Theoretically and experimentally, decreasing the diameter of microfiber and choosing proper 2D materials with high thermal conductivity and high photothermal conversion efficiency can effectively improve the modulation rate by accelerating the heat generation and dissipation processes. In recent years, microfiber knot resonator (MKR), fabricated by knotting a microfiber into a ring, has attracted great attentions for its potential applications in filters, optical buffers, routers and logic gates. [1] The microfiber diameter of MKR is as small as a few micrometers and even sub-micrometers, [19,20] significantly thinner than those in MZI-and MI-based modulators, suggesting that MKR can be able to realize a faster response behavior. In addition, the small microfiber diameter guarantees sufficient interactions between the strong evanescent field of MKR and other materials, implying that MKR can be easily devised as various all-optical devices. [21] Moreover, it was reported that the ring diameter of MKR is only ≈0.3-1 mm, [20,[22][23][24][25] endowing MKR with many advantages such as compact size and good antiinterference. On the other hand, as a new promising 2D material, MXene is verified to possess high thermal conductivity [26] All-optical devices based on 2D materials have attracted great attention for desirable applications, such as communications and signal processing. However, the previously reported all-fiber all-optical devices utilizing the interferometer structures greatly limit their practical applications due to the poor anti-interference ability and slow modulation rate. In this work, an all-optical device has been demonstrated based on a microfiber knot resonator (MKR) deposited with Ti 2 CT x...

2D graphene with tremendous novel properties is an ideal material for optical and optoelectronic applications. Meanwhile, photonic crystal fibers (PCFs) have been recognized as next-generation optical fibers that possess a designable porous structure, rich functions, and different working mechanisms. Recently, the integration of graphene with a PCF has formed a new hybrid fiber, a graphene photonic crystal fiber (Gr-PCF), which exhibits an extremely strong and tunable light-matter interaction across a broadband spectrum range and opens up a new interdisciplinary research direction. In this review, recent studies on, and achievements in graphene-traditional fibers and Gr-PCFs have been summarized from the aspects of the development process, preparation method, and device application. First, the graphene properties and the development and characteristics of PCFs are introduced. The discussion is continued with the existing fabrication technologies for hybrid graphene-traditional fibers. Next, the chemical vapor deposition method for Gr-PCFs is elaborated. Then, fiber devices based on graphene-traditional fibers, Gr-PCFs, and other 2D material fibers are presented. To conclude, challenges and perspectives are presented to encourage advanced Gr-PCF study.
