In recent years PCFs made of silica and
air hole has provided a new approach for dispersion compensation. For
dispersion compensating fibers , large negative dispersion D(ps/km-nm)is
required. To maintain the flat and zero dispersion in photonic crystal fiber
(PCF) different air hole diameter and different pitches has been introduced.
These differences in diameter and pitches gives different dispersion graphs and
after comparison we get that design which has lowest dispersion among them. This
paper proposes a new geometry of PCFs which uses ‘Circular’ holes instead of square
or elliptical holes which gives large negative dispersion without high doping .
Keywords: circular hole PCF; dispersion compensation ; negative dispersion.
