Analysis of All-Solid Microstructured Bend-Insensitive Optical Fiber
A novel bend-insensitive optical fiber is proposed. Low-index rods are included in the cladding to reduce the bending loss, and low refractive index ring surrounding the core is used to remove the higher-order mode. Index-contrast between the core and the low-index ring is conserved to ensure low splicing loss in standard single-mode optical fiber. The bending loss of the fundamental mode and the confinement loss of the higher-order mode are investigated by the finite-element method. The splicing losses between the bend-insensitive optical fiber and the single-mode optical fiber are investigated by the beam propagation method. The results show that the bending loss of the proposed fiber can meet the G.657 A1 standard and the splicing loss between the bend-insensitive optical fiber and the single-mode optical fiber is less than 0.08 dB.
