Abstract

Fiber nonlinearities are more enhanced in Photonic Crystal Fibers (PCFs) due to their extremely small Mode Field Diameters (MFDs). One of the outcomes of these nonlinearities is self phase modulation (SPM). SPM makes a Gaussian pulse propagating in a nonlinear, non dispersive medium to undergo frequency chirping without changing its temporal envelope. This generates additional frequency components in the pulse causing spectral broadening. Such a phenomenon can be further explored in designing broad band coherent light sources to be used in wavelength division multiplexing systems. A quick method to estimate the amount of spectral broadening in PCFs is presented.
