Dispersion compensating photonic crystal fiber using double-hole assisted core for high and uniform birefringence

Abstract

A novel photonic crystal fiber design is presented. The design provides broadband high and uniform birefringence, large negative dispersion and low confinement loss. The fiber is based on double-hole assisted core in the conventional square lattice cladding. For the proposed PCF, high and uniform birefringence of 7.5 x 10(-3), the negative dispersion of -150 ps/(nm km) and an extremely low confinement loss can be obtained over E+ S+C+L+U (1380 similar to 1780 nm) wavelength bands.
