Abstract

We use numerical simulations to investigate how the curvature of the fiber core boundary influences the attenuation of hollow antiresonant fibers. We show the importance of a “negative” curvature core boundary in reducing confinement losses and also how, for certain curvatures, optical power is coupled resonantly to cladding modes. We simulate bending losses and find results in agreement with previously-reported experiments.

Design of a negative curvature fiber: modification of the NCF geometry is obtained by moving the point C along the straight line OA. In this way the fiber structure passes from “a “ to “c,” as shown on the left hand side. The fiber core radius is kept fixed at 47μm.

Relationship between confinement losses (blue line with dots, left axis) and normalized curvature of a NCF. The values of the effective mode area of the NCF (red line with triangles) are indicated on the right axis. On the right hand side is a magnification of the same plot for values of the normalized curvature between 0.9 and 1.

The air core mode (blue - A) and a silica cladding mode (red - B) cross at the value of the curvature corresponding to the loss peak in the confinement loss curve (shown in green). Poynting vector plots are shown on the right: C is a low-dispersion (air) cladding mode.

The relationship between confinement losses and bend radius is strongly affected by the coupling between air-core and cladding modes, which causes some peak losses. The wavelength associated to these peaks also depends on the particular bend radius adopted.
