Abstract
A method of processing an out-coupling end of a hollow core fiber including a plurality of anti-resonance elements surrounding a hollow core, and a hollow core fiber having been so processed. The method may include performing a tapering step to form a taper in the anti-resonance elements; performing a cleaving step at the taper to form at least one tapered out-coupling end of the hollow core fiber; and performing an end processing step including further heating the out-coupling end in a controlled manner to smoothen the out-coupling end.
