Abstract :
This paper numerically describes the design of double-cladding photonic-crystal fiber (DC-PCF) for ultrabroadband compensation over all telecommunication bands (O to L), i.e., ranging from 1260 to 1625 nm. We show that an ultrabroadband compensating DC-PCF can be designed simply by considering the zero-dispersion wavelength and the relative dispersion to the slope at a particular wavelength of a conventional single-mode fiber (SMF). As a result, we reveal that the proposed DC-PCF can successfully compensate for the dispersion of a conventional SMF with an effective dispersion range of plusmn0.4 ps/nmmiddotkm over all telecommunication bands as well as provide an effective area comparable to that of conventional dispersion-compensating fiber
