Abstract
A hollow-core photonic crystal fiber (HC-PCF) () for guiding at least one mode of a light field () along a mode guiding section () of the HC-PCF (), comprises an outer jacket (), an inner cladding () and a hollow core (), which extend along the HC-PCF (), wherein the inner cladding () is arranged on an interior surface of the outer jacket () and comprises anti-resonant structures () surrounding the hollow core (), and the hollow core () has a mode guiding core diameter (d) provided along the mode guiding section of the HC-PCF (), and wherein at least one fiber end () of the HC-PCF () has a light field coupling section () in which the hollow core () is tapered over an axial coupling section length from a fiber end core diameter (D) at the at least one fiber end () to the mode guiding core diameter (d). Furthermore, methods of using the HC-PCF and manufacturing the HC-PCF are described.
