  • Hollow-Core Photonic Crystal Fiber and Method of Manufacturing thereof
    Publication number: 20200166699
    Abstract: A hollow-core photonic crystal fiber (HC-PCF)(10) for guiding at least one mode of a light field(1) along a mode guiding section(11) of the HC-PCF(10), comprises an outer jacket(12), an inner cladding(13) and a hollow core(14), which extend along the HC-PCF(10), wherein the inner clad-ding(13) is arranged on an interior surface of the outer jacket(12) and comprises anti-resonant structures(15) surrounding the hollow core(14), and the hollow core(14) has a mode guiding core diameter(d) provided along the mode guiding section of the HC-PCF(10), and wherein at least one fiber end (16) of the HC-PCF(10) has a light field coupling section(17) in which the hollow core(14) is tapered over an axial coupling section length from a fiber end core diameter(D) at the at least one fiber end (16) to the mode guiding core diameter(d). Furthermore, methods of using the HC-PCF and manufacturing the HC-PCF are described.
