High Resolution Imaging Microstructured Optical Fibres

Applications and Development of Multi-Core Optical Fibers

“…Based on the design of the fiber's geometry and optical characteristics, various high-precision chemical vapor deposition methods are used to produce core rods, cladding rods, and auxiliary rods. These prepared rods are then combined using methods such as grinding [44,144,145] and stacking [46,[146][147][148][149][150][151][152][153], rod drilling [45,[154][155][156][157], and other improved and novel techniques [158][159][160][161][162][163][164][165][166][167][168][169][170][171]. The resulting multi-core fiber preform is then drawn into a multi-core fiber through a series of processes.…”

“…With the continuous cross-disciplinary development of optical fibers and other fields, the fabrication process of multi-core optical fibers has also been continuously updated and iterated. In recent years, researchers have introduced 3D printing technology for the fabrication of multi-core optical fibers [161][162][163][164][165][166][167][168][169][170][171], or have improved the rod-in-tube stacking method [158][159][160].…”

“…In 2015, Cook K., Canning J., and others proposed the use of 3D printing technology for the fabrication of air-hole preform rods for optical fibers [161,162]. Subsequently, it has gradually been used for the fabrication of single-mode fibers [163][164][165][166][167], photonic crystal fibers [168,169], and multi-core optical fibers [170,171]. The fabrication of multi-core optical fibers using 3D printing is based on the rod-in-tube drilling method.…”
