Complete Process of Hollow-Core Fiber Processing
In this paper, we comprehensively review the progress in the development of HCFs including fiber design, fabrication and parameters (with comparisons to conventional single-mode fibers) and support technologies like splicing and testing. Hollow core fiber is a type of optical fiber that guides light through an air core rather than solid glass. The air core is surrounded by a cladding composed of delicate microstructures, which confines light to the hollow core using photonic bandgap or anti-resonance mechanisms. Fused silica glass becomes fluid at temperatures greater than 1400°C and hence most. Methods are known for producing an anti-resonant hollow-core fiber which has a hollow core extending along a fiber longitudinal axis and an inner jacket region that surrounds the hollow core, said jacket region comprising multiple anti-resonant elements.
