Abstract

A reply to the Comment by Mortensen et al. [Appl. Opt. 47, xxxx–xxxx (2007)] on our previous paper on on our earlier paper published in [Appl. Opt. 46, 3263–3268 (2007)APOPAI0003-6935is presented. In the theoretical study of a highly dispersive dual concentric-core pure silica photonic crystal fiber, we presented a design wherein the high value of the dispersion coefficient was due to coupling of modes between two asymmetric cores at a phase-matched wavelength of $1.55\mathrm{\mu m}$. In the condition in which both the supermodes are excited simultaneously, the dispersion effects of the two modes do not cancel each other, but the final dispersion coefficient depends on the input launching condition. We also predict the feasibility of manufacturing low-loss pure silica dual concentric-core photonic crystal fibers in future with advancement in the current fabrication techniques.
