| 摘 要： | There has been an increasing interest in rare-earth-dopedpolymer optical fiber (POF) because of its applicationsin optical communication systems and optical sensors,especially in local networks and data communications[1].In recent years, much work has been done on rare-earth-doped POFs, such as Nd3+, Eu3+, Sm3+, Er3+-dopedPOFs[2-5]. Amplified spontaneous emission (ASE) wasfound in Nd3+-doped POFs[2] and Eu3+-doped gradedindex POFs[6]. However the clusters of rare-earth ionsexist in t…
