Abstract
The loss characteristics of two kinds of typical single-HE11-mode Bragg fibers based on PES/As2Se3 and Si/SiO2-multilayer claddings are analyzed theoretically. The available lowest loss levels and corresponding structure parameters of the two single-HE11-mode Bragg fiber are optimized to show the feasibility of the low-loss single-HE11-mode Bragg fiber design under the two material systems. The influences of structure parameters on the loss characteristics are analyzed in detail. For PES/As2Se3 Bragg fiber, a loss level as high as 105–107 dB/km is expected at wavelengths from 0.85 to 2.94 μm due to the large absorption loss. To extend the limitation, lower loss cladding material should be investigated. For Si/SiO2 Bragg fiber, low-loss single-HE11-mode propagation can be achieved by the materials if fabrication improvement can support long fabricated fiber length.
