Abstract

As a kind of hollow-core optical waveguide, the optical field can be bound in the core of anti-resonance hollow-core fibers, so it can effectively overcome the ordinary quartz glass absorption loss in the mid-infrared band. In this paper, we use FEM (finite element method) to theoretically calculate the transmission characteristics of a non-node anti-resonance hollow-core fiber over the mid-infrared range of 2-5μm. The influence of the micro-nano structure wall thickness on the transmission spectrum of this novel hollow-core fiber is studied. Simultaneously, the relationship between the wall thickness and the high-loss resonance peak bandwidth is discussed. The results show that the transmission characteristics of this fiber match well with those of ARROW (Anti-Resonant Reflecting Optical Waveguide) model. With the increase of the micro-nano structure wall thickness, the first-order high-loss resonance peak is obviously “red-shifted” and its bandwidth increases linearly. When the wall thickness of the micro-nano structure is about 1μm, the transmission loss of the fiber in the mid-infrared band is small. This work has provided some references for the experimental research on the nonlinear effect of the fiber in the mid-infrared band.
