Dispersion compensating Photonic Crystal Fibers

Photonic Crystal Fiber (PCF) is a pure silica optical fiber where microstructured air-holes run along the entire length of it. Since 1995, PCF have generated a lot of interest due to their remarkable properties like endlessly single mode from UV to IR region, generation of supercontinuum etc. The unusual dispersion properties like zero dispersion at any wavelength, ultraflattened dispersion arises due to the flexible geometry in the cladding. Scalar effective index model has been used to obtain the dispersion properties of PCFs. The dispersion due to the photonic crystal cladding has been considered. The high negative dispersion characteristic of PCF makes them a suitable candidate for dispersion compensating applications.
