| Abstract: | The confinement-loss characters of hollow OmniGuide fibers (OGFs) are investigated. The OGFs with different cross-section geometric parameters have been analyzed with the aim of finding how parameters (such as core radius, thickness and number of cladding layer) are responsible for the fabricated low-loss hollow OGFs. It is shown that hollow OGFs can uniquely access less confinement loss unavailable to conventional Bragg fibers. We also derive the formulas for core radius, thickness and number of cladding layers. These results would be helpful for optimization designs and applications of low-loss hollow OGFs. |
