“…Issa et al [15] have experimentally realized elliptical air-hole PCFs with birefringence of 1×10 −4 in 2004. Li et al [16] and Wang et al [17] have demonstrated birefringent PCFs by combining circular and elliptical air holes, and the corresponding birefringences were 1.09×10 −2 and 2.54×10 −2 , respectively. However, it is difficult to fabricate PCFs with both circular and elliptical air holes.…”

A new type of V-shaped photonic crystal fiber with elliptical air-holes is proposed to realize simultaneous high birefringence and nonlinearity at a wavelength of 1.55 µm. The full vector finite element method was adopted to investigate its characteristics, including birefringence, nonlinearity, and dispersion. The PCF exhibited a very high birefringence of 2.89×10 −2 and very high nonlinear coefficient of 102.69 W −1 •km −1 . In particular, there were two zero-dispersion wavelengths (ZDWs) in the visible (X: 640-720 nm and Y : 730-760 nm) and near-infrared regions (X: 1050-1606 nm and Y : 850-1500 nm). The combination of high birefringence and nonlinearity allowed the PCF to maintain the polarization state and generate a broadband super continuum, with potential applications in nonlinear optics.
