We developed a high-throughput technique to design photonic crystal fiber (PCF) structures with desired properties and functionalities. By using a genetic algorithm, a high birefringence and an ultra-flattened chromatic dispersion over a large wavelength range are achieved. It is shown that a low confinement loss can be obtained while the birefringence remains the same. The numerical results show that the presented PCF structure can be successfully employed as maintaining polarization devices working in a large zero- chromatic dispersion region.
