The photonic bandgaps (PBGs) of honeycomb photonic bandgap fibers (HPBFs) with and without interstitial air holes (IAHs) are numerically investigated. It is shown that the IAHs can increase the width of PBGs in HPBFs, and also that at the same moderate total air filling fraction, HPBFs with IAHs produce more uniform PBGs than those without IAHs. The bandgap behavior is qualitatively explained using the node-and-vein concept.
