中文摘要 | a theoretical method to analyze a kind of four-layer large flattened mode (lfm) fibers is presented. the properties of the fiber, including the fundamental and higher-order modal fields, effective area and bending loss are discussed by comparison. at the same time, the reasons for the different characteristics are considered. the obtained results indicate that the effective area of the four-layer lfm fiber is about 1.3 times larger than that of the conventional standard step-index fiber and the fiber can suppress the higher-order modes via bending effectively. the four-layer lfm fiber has less efficient bend-induced filtering ability than the conventional step-index fiber; however, it has more efficient filtering ability than the three-layer lfm fiber.
