In this study, a gas-filling mechanism was constructed for an Antiresonant Hollow-Core Fiber (AR-HCF) for its application as a gas cell in spectroscopic measurements. A method for suppressing spectral interference fringes by bending AR-HCF was investigated. Specifically, the fringe suppression effect was compared by varying the fiber's radius of curvature. The results demonstrate that a smaller radius of curvature leads to more effective suppression of the interference fringes, enabling a clearer observation of gas absorption lines.
