Abstract
A hollow-core fiber () of non-bandgap type comprises a hollow core region () axially extending along the hollow-core fiber () and having a smallest transverse core dimension (D), wherein the core region () is adapted for guiding a transverse fundamental core mode and transverse higher order core modes, and an inner cladding region () comprising an arrangement of anti-resonant elements (AREs) (A,B) surrounding the core region () along the hollow-core fiber (), each having a smallest transverse ARE dimension (d) and being adapted for guiding transverse ARE modes, wherein the core region () and the AREs (A,B) are configured to provide phase matching of the higher order core modes and the ARE modes and the ARE dimension (d) and the core dimension (D) are selected such that a ratio of the ARE and core dimensions (d/D) is approximated to a quotient of zeros of Bessel functions of first kind (u/u), multiplied with a fitting factor in a range ofto, with m being the m-th zero of the Bessel function of first kind of order, said zeros of the Bessel functions describing the LPARE modes and LPhigher order core modes, respectively. Furthermore, an optical device () including the hollow-core fiber () and a method of manufacturing the hollow-core fiber are described.
