ABSTRACT Anti‐resonant hollow core fibres have significant advantages derived from the guidance of light in air, and have been rapidly developed and employed in the near and mid‐infrared. Despite comparable or greater benefits in the visible and ultraviolet, their development and uptake has been slow due to inherent challenges in their fabrication. In this perspective, we provide a brief look at these fabrication challenges, possible solutions and potential applications for hollow core fibres in the short‐wavelength limit.
