Birefringence Analysis of Photonic-Bandgap Fibers Using the Hexagonal Yee's Cell

Abstract: Abstract-A full-vectorial finite-difference scheme utilizing the hexagonal Yee's cell is used in this paper to analyze the modes of photonic-bandgap fibers with C 6 symmetry. Because it respects the fiber's native symmetry, this method is free from any numerical birefringence. We also incorporate in it techniques for reducing the memory requirement (up to 3 to 4 times) and computational time, in particular by exploiting some of the symmetry properties of these fibers. Using sub-pixel averaging, we demonstrate … Show more

“…A number of alternative methods have therefore subsequently been newly derived, or adapted from existing approaches, to allow the study of realistic fibre structures incorporating core defects and periodic claddings of finite extent. These second-generation studies were based on, for example, plane-wave expansion [25], finite element [26], multipole [27] or finite difference methods [28]. The downside of all these brute-force numerical techniques is that they fail to capture and explain the physical mechanisms generating the PBG and do not provide any insight into how structural perturbations of the cladding periodicity and/or distortions at the defect termination affect the optical properties of the fibre.…”
