Abstract: | In a recent paper, Subbaraman et al. [Appl. Opt. 46, 3263-3268 (2007)] reported a theoretical and numerical study of highly dispersive pure silica photonic crystal fiber supporting group-velocity dispersion exceeding -2x10(4) ps/nm/km. This Comment argues that the authors consider only one of two sides of the same coin by not taking the corresponding beating length into account. |
