摘要
In this paper, a new type of dispersion compensating photonic crystal fiber with highly birefringence is proposed. In this fiber both core and cladding consist of octagonal lattice air holes, elliptical air holes in the core and circular air holes in the cladding. Birefringence, dispersion and field distribution of the fundamental modes are investigated by using the finite difference time domain method. The simulation results show that it can obtain a negative dispersion of about -100 to -200 ps/(nm km) and birefringence over 2 x 10(-2) in the entire S to L telecommunication bands.
