The photonic bandgaps and modal properties of triangular lattice photonic bandgap photonic crystal fibers (PBG‐PCFs) with interstitial holes are analyzed by the full‐vector plane‐wave expansion method. We analyzed the influence of the air holes array triangular lattice cladding and the interstitial holes on the photonic bandgaps and calculated the spectrum range of photonic bandgaps. We found that the PBG‐PCFs with interstitial holes have a fundamental bandgap and a secondary bandgap. The transmission spectrum of PBG‐PCFs is measured. The results indicate that there are two strong transmission bands in the near‐infrared, but hardly any transmission phenomena in the visible region, which show that there are some bandgaps in near‐infrared wavelength. The results of the experiments are consistent with the numerically simulative results using the full‐vector plane‐wave expansion method. © 2011 Wiley Periodicals, Inc.
