Based on the modified dual core structure, three kinds of special photonic crystal fibers are presented, which are extremely large negative dispersion, super‐broad band, and large area mode field dispersion‐compensating photonic crystal fibers (DCPCF). For extremely large negative dispersion DCPCF, the peak of negative dispersion reaches −5.9 × 104 ps/(nm km). Super‐broad band DCPCF has broadband large negative dispersion and the dispersion value varies linearly from −380 ps/(nm km) to −420 ps/(nm km) in the C band. The designed large area mode field DCPCF has a peak dispersion of −1203 ps/(nm km) with the inner core mode area of 47 μm2 and outer core mode area of 835 μm2. Furthermore, for the large area mode field DCPCF, the experimental result is also obtained. © 2008 Wiley Periodicals, Inc.
