“…The proposed PCF has circular air holes of two different diameters alternating in the cladding, plus a silica defect at the center. Preliminary results for the proposed design have been published in conference proceedings [19][20][21]. However, in this paper, we show progress in control of multiple optical properties such as high birefringence, large normal dispersion, and single-mode operation at the same time.…”

In this study we propose a new photonic crystal fiber (PCF) design that simultaneously offers broadband single-mode operation, high birefringence, and large normal dispersion in the optical-communication wavelength regime. The waveguide is based on a hybrid square-lattice PCF (HS-PCF) that has circular air holes of two different diameters alternating in the cladding, plus a pure silica defect at the center. The optical properties of the guided modes are analyzed numerically by the finite-element method (FEM) with a perfectly matched layer as the boundary condition. The optimized HS-PCF has a dispersion coefficient of -601.67 ps nm -1 km -1 and a high birefringence of 1.025×10 -2 at 1.55 µm. In addition, over the S+C+L+U wavelength bands the proposed HS-PCF with ultraflat birefringence with a slope on the order of 10.

“…The distinctive properties of PCFs are the high design flexibility [2], [8]. It is possible to obtain PCFs with diametrically opposite properties by changing the geometric characteristics of the air-holes in the fiber crosssection, that is, their dimension or position.…”

Photonic crystal fibres -micro structured fibre consisting of air hole arrays running along its length-have attracted much attention for fibre device application because of its unusual optical properties that are not realized in standard optical fibre, such as high birefringence, high nonlinearity, low confinement loss and tailorable chromatic dispersion. High birefringent PCF can be designed by breaking the circular symmetry and implementing asymmetric defect structures such as dissimilar air hole diameter, varying the number of circular and elliptical air holes. This paper proposes a highly birefringent PCF with ultra-low confinement loss by introducing four ring solid core hexagonal structure which having both elliptical and circular air holes and introducing large air hole diameters near the core region for making the asymmetry. The modal birefringence, refractive indices, confinement loss and chromatic dispersion are calculated by using Finite element method (FEM). An endlessly single mode, high birefringent (05.152x10 -3 ) and a low confinement loss (7.85x10 -5 dB/km) found at the excitation wavelength of λ=1550nm with only four rings of air holes in the fiber cladding.

Abstract: We have proposed a hybrid square-lattice PCF and numerically investigated its birefringence and dispersion. Based on the plane wave expansion method, it is shown that the proposed structure provides high birefringence and flattened dispersion property.
