具有高双折射特性的空芯反谐振光纤
High-birefringence hollow-core anti-resonant fiber
摘要
Abstract
To solve the problems of complex fiber structure and high manufacturing difficulty in existing methods of improving the birefringence of optical fibers,a hollow-core anti-resonant fiber with high birefringence characteristics is designed.The cladding of the optical fiber is composed of a cladding ring,four half-tubes,and a pair of small circles nested inside the half-tubes.The finite element method is used to analyze the influence of the structural parameters of the fiber on its birefringence,transmis-sion loss,confinement loss,and absorption loss.The simulation results show that changing the diameter of the half-tube has a small effect on the birefringence.By adjusting the thickness difference between the horizontal and vertical half-tubes in the fiber,the fiber can achieve high birefringence,with a birefringence greater than 1.5×10-4 over a wide frequency range of 0.25 THz,while maintaining a transmission loss less than 10 dB/m.关键词
