Numerical analysis of a circular chalcogenide/silica hybrid nanostructured photonic crystal fiber for the purpose of dispersion compensation

Abstract

AbstractIn this paper, we report the numerical analysis of a nanostructured photonic crystal fiber for making an efficient dispersion‐compensating medium. For our computational studies, the core of the proposed structure is made up of As2Se3, and the cladding structure is a mixture of air holes and holes filled with silica. Our simulations indicate that the chromatic dispersion and the confinement loss at the wavelength of 1.55 µm is −3280 ps/nm/km and 1.71 × 10−6 dB/m respectively. Moreover, the relative dispersion slope at the wavelength of 1.55 µm is computed to be 0.00357 nm−1 that closely matches that of the conventional fibers at the third window. The effect of changing the dimensions of the holes in the first ring and also the distance between the adjacent holes (Λ) in the same ring on chromatic dispersion are also studied. The presented structure is an efficient dispersion‐compensating medium. Copyright © 2016 John Wiley & Sons, Ltd.
