    "abstract": "We study the dispersion and leakage properties for the recently reported\nlow-loss photonic band-gap fiber by Smith et al. [Nature 424, 657 (2003)]. We\nfind that surface modes have a significant impact on both the dispersion and\nleakage properties of the fundamental mode. Our dispersion results are in\nqualitative agreement with the dispersion profile reported recently by Ouzounov\net al. [Science 301, 1702 (2003)] though our results suggest that the observed\nlong-wavelength anomalous dispersion is due to an avoided crossing (with\nsurface modes) rather than band-bending caused by the photonic band-gap\nboundary of the cladding.",
