Abstract:

The polarization properties and propagation characteristics of polymer photonic crystal fibres with elliptical air-holes and hexagonal structure are investigated by using the full vectorial plane wave method. The results show that the birefringence of the fibre is induced by asymmetries of the cladding. Moreover, by adjusting the elliptical ratio of cladding, we find the optimized design parameters of the fiber with birefringence, operating in a single mode regime at an appropriate wavelength range. The range of wavelength is consistent with the communication windows of polymer optical fibres, and elliptical ratio of cladding , this fibre is able to exhibit high birefringence of .This conclusion is useful for preparing high birefringence polymer photonic crystal fibers.

Key words: fiber and waveguide optics, polarization properties, full vectorial plane wave method, polymer, optical fibers, high birefringence
