全固态大模场光子晶体光纤的研究
Study on all-solid large mode area photonic crystal fibers
摘要
Abstract
Fiber lasers have huge advantages compared with the traditional lasers.This paper proposes a novel all-solid square-lattice Yb3+-doped Photonic Crystal Fiber (PCF)for the development of fiber lasers with still better output characteristics and simulates its structure and properties by using the Finite Element Method (FEM).By designing defect positions and optimizing the sizes of B2 O3-doped rods,it enables the Mode Field Area (MFA)of the fundamental mode of this fiber to reach 4 405μm2 at 1.06μm and satisfy the conditions for single-mode transmissions and low bending loss properties at the same time,i.e. maintaining single-mode transmissions when the bending radius is larger than 8 cm.This PCF can be used as a gain fiber in high power fiber lasers.关键词
