一种新型高双折射光子晶体光纤特性研究
Investigation of a new kind of high birefringence photonic crystal fiber∗
摘要
Abstract
A kind of highly birefringent and highly nonlinear photonic crystal fiber (PCF) is proposed. The fundamental mode field, birefrin-gence, nonlinear coefficient, effective mode area and dispersion characteristic of the fiber are studied by the full-vector finite element method. Simulation results show that the birefringence becomes larger by reducing the air hole pitch, and the birefringence reaches up to 10−2 at a wavelength of 1550 nm, which is about two orders of magnitude higher than that of the regular elliptic polarization maintaining fiber. At the same time, a nonlinear coefficient of 42 W−1 ·km−1 is obtained. There are two zero dispersion wavelengths in the visible and the near-infrared region respectively, and flattened chromatic dispersion from 800 nm to 2000 nm is obtained. Such a design provides a new approach to obtaining highly birefringent and highly nonlinear PCF, and the fiber has a broad prospect of application in the polarization control, nonlinear optics and dispersion control.关键词
