The existence of surface modes is the main drawback and the reduction of the fiber losses is not sufficient in 6-fold symmetry air-guiding photonic bandgap fibers (PBGFs). We show that the surface mode free condition is expressed as a normalized silica-ring thickness T = 0.5 for any core size and the cladding structural parameters, regardless the core radius of the silica-ring is one of the main factors of dominating the surface mode’s condition, and the fact that the wavelength range of the photonic bandgap (PBG) changes on varying the structural parameters of the cladding. Moreover, we propose a novel type of PBGF, namely 3-fold symmetry 27 cell-core PBGF without surface mode, which exhibits lower scattering losses caused by surface roughness of the silica-ring in comparison to 6-fold symmetry 19 cell-core PBGFs and suppresses the mode coupling between fundamental-like and higher-order modes when compared to 6-fold symmetry 37 cell-core PBGFs. |
