“…After the phase matching wavelength ( > ) (Figure 2(c)), the fundamental mode field distribution is in the outer core region. Due to the redistribution of modal fields, there is a rapid change in the slope of effective index around the phase matching wavelength, leading to a large negative dispersion [9,20,21].…”

A highly dispersive dual core quasi-periodic photonic crystal fiber is proposed for chromatic dispersion compensation. The dispersion for the dual concentric core fiber is optimized to compensate the chromatic dispersion with a high negative dispersion, accomplishing the communication bandwidth from S-band (1460 nm) to L-band (1625 nm). By precise control of structural parameter we have achieved a maximum dispersion of −18,838 ps/nm-km with the phase matching wavelength centred around 1.55 μm. We also numerically investigate the influence of structural parameter and doping effects and its response on peak dispersion parameter.
