“…Several reviews related to their fabrication and uses are available [5,8,9,12,28,46,56,[65][66][67][68]. Optical nanofibres are typically made by tapering a section of commercial optical fibre via heating and stretching [4,56,[69][70][71] in a fibre pulling rig, with either a stationary or moving (brushing) heat source. Different heat sources may be used, depending on the compound and melting point of the glass [8], such as a CO 2 laser [72], resistance heating [73] or a graphite microheater [74].…”

Nanofibre-based optical cavities are particularly useful for quantum optics applications, such as the development of integrated single-photon sources, and for studying fundamental light-matter interactions in cavity quantum electrodynamics (cQED). Although several techniques have been used to produce such cavities, focussed ion beam (FIB) milling is becoming popular; it can be used for the fabrication of complex structures directly in the nanofibre. However, it is challenging to mill insulating materials with highly curved geometries and large aspect ratios, such as silica nanofibres, due to charge accumulation in the material. In this article, we highlight the main features of nanofibres and briefly review cQED with nanofibre-based optical cavities. An overview of the milling process is given with a summary of different FIB milled devices and their applications. Finally, we present our technique to produce nanofibre cavities by FIB milling. To overcome the aforementioned challenges, we present a specially designed base plate with an indium tin oxide (ITO)-coated Si substrate and outline our procedure, which improves stability during milling and increases repeatability.

“…The technique comprises three steps for conventional flame-brushing and pulling, recalibration, and one-directional pulling. Using this method, the microfiber with 1.6 μm diameters, 500 mm uniform lengths with <66 nm diameter variances, and high transmittances of 91.5% is fabricated [126]. With the larger diameter of 5 μm, the microfiber length could be up to 165 cm [127].…”

AbstractDue to the exotic electronic and optical properties, two-dimensional (2D) materials, such as graphene, topological insulators, transition metal dichalcogenides, black phosphorus, MXenes, graphitic carbon nitride, metal-organic frameworks, and so on, have attracted enormous interest in the scientific communities dealing with electronics and photonics. Combing the 2D materials with the microfiber, the 2D material-decorated microfiber photonic devices could be assembled. They offer the advantages of a high nonlinear effect, all fiber structure, high damage threshold, and so on, which play important roles in fields of pulse shaping and all-optical signal processing. In this review, first, we introduce the fabrication methods of 2D material-decorated microfiber photonic devices. Then the pulse generation and the nonlinear soliton dynamics based on pulse shaping method in fiber lasers and all-optical signal processing based on 2D material-decorated microfiber photonic devices, such as optical modulator and wavelength converter, are summarized, respectively. Finally, the challenges and opportunities in the future development of 2D material-decorated microfiber photonic devices are given. It is believed that 2D material-decorated microfiber photonic devices will develop rapidly and open new opportunities in the related fields.

Nanofibre-based optical cavities are particularly useful for quantum optics application, such as the development of integrated single-photon sources, and for studying fundamental light-matter interactions in cavity quantum electrodynamics (cQED). Although several techniques have been used to produce nanofibrebased optical cavities, focussed ion beam (FIB) milling is becoming popular; it can be used for the fabrication of complex structures directly in the nanofibre. This technique uses a highly accelerated ion beam to remove atoms from the target material with high resolution. However, it is challenging to mill insulating materials with highly-curved structures and large aspect ratios, such as silica nanofibres, due to charge accumulation in the material that leads to mechanical vibrations and misalignment issues. In this article, we highlight the main features of nanofibres and briefly review cQED with nanofibre-based optical cavities. An overview of the milling process is given with a summary of different FIB milled devices and their applications. Finally, we present our technique to produce nanofibre cavities by FIB milling. To overcome the aforementioned challenges, we present a specially designed base plate with an indium tin oxide (ITO)-coated Si substrate and outline our procedure, which improves stability during milling and increases repeatability.
