| Abstract: | Based on light-waveguide and matrix theory,the theoretical light transmission model is set up to analyse the hollow-core Bragg fiber.The unequal-period Bragg fiber structure is simulated in order to get the minimum out-flowing flux.The fiber with eight cladding-layers is obtained through optimum design,and its loss characteristic is analyzed.This simple structure is very useful for the fabrication and application of Bragg fiber due to its low loss and small number of cladding layers. |

| Keywords: | fiber optics Bragg fiber transfer matrix radial out-flowing flux loss |
