Description
Summary:This paper presents a broadband dispersion-compensating photonic crystal fibre (B-DCPCF) with a high compensation ratio of 30:1. We theoretically tailored the negative dispersion in a photonic crystal fibre (PCF) to nullify the positive dispersion in the transmission fibre over a bandwidth range of as wide as possible. The numeric results indicate that the effective dispersion within ±0.64 ps/nm/km over a bandwidth range of 226 nm (from 1338 to 1564 nm), cover the E + S + C wavelength bands. Finally, the confinement loss and the modal properties were examined to verify that the proposed B-DCPCF with extremely low confinement loss and should be operated in single mode throughout the operating band.
