Hollow-Core Optical Fibers Offer Advantages at Any Wavelength Feb 25, 2019 — Conventional optical fibers are fabulously successful, but they have profound limitations. These include a finite spectral transparency, susceptibility to optical damage, dispersion — which restricts the ability to deliver short and ultrashort pulses — and nonlinear optical response. Such limitations are fundamental to conventional optical fibers because the light travels through a solid or a liquid material. In most conventional fibers, fused silica is the material that forms
