28 Sep 2017 | | Abstract: | This paper presents a photonic crystal fiber (PCF) with heptagonal core and
heptagonal cladding for dispersion compensation. Different optical properties
of the suggested PCF are explored using the finite element method (FEM). The
proposed dispersion compensating PCF (DC-PCF) exhibits a very large negative
chromatic dispersion of $-940 ps/(nm-km)$ at $1550 nm$ wavelength. The overall
dispersion of the DC-PCF is $-420.1$ to $-1160 ps/(nm-km)$ in the wavelength
range of $1390$ to $1700 nm$ ($310 nm$ band). The relative dispersion slope is
$0.0036 nm^{-1}$ which is a perfect match with the standard single mode fibers.
Moreover, it exhibits a very low confinement loss of about $10^{-5} dB/km$ and
low nonlinearity of $45 W^{-1}km^{-1}$ at $1550 nm$ wavelength. Since the
suggested DC-PCF has very high negative dispersion and low nonlinearity, it can
be a potential candidate for broadband dispersion compensation in fiber-optic
communication. | | Source: | arXiv, 1710.0068 | | Services: | Forum | Review | PDF | Favorites | |
