【 摘 要 】

The spectral and amplitude sensitivities of the HE11 mode in a hollow-core Bragg fiberwith or without gold layer are investigated by using an analytical method. This method is applied fordifferent structures without or with a gold layer made from 11, 9, 8, and 5 layers. The amplitudesensitivity at the minimum-loss wavelength increases when the number N of the layers increases fromN = 5 to N = 11. When a high index material just before the outermost region of a hollow-core Braggfiber is replaced by a gold layer, the optical confinement for the HE11 mode in the core increasesabout two times.
