Photonic crystal fiber (PCF) provides a unique platform for realizing the desired dispersion, birefringence, confinement, and mode multiplicity characteristics for myriad of applications. This can be attributed to the freedom in designing the shape, size and arrangement of holes and material composition of the PCF. Using the vector finite element method (VFEM) mode solver in OptiMode, modal analysis of arbitrary PCF designs can be performed, and the linear/nonlinear fiber model characteristics can be extracted. The parameters of the PCF can be used in OptiSystem to simulate the evolution of signals and to asses system performance.
