摘要：

The fiber-structure dependence of the gain characteristics of Er3+ doped fibers pumped at 1.48 µm is described. The optimum V value is derived theoretically and experimentally. For step-index fibers, the optimum V value is 1.6, which is smaller than that needed to minimize spot size. The fiber with a small V value enjoys a large Er3+ confinement effect. For laser diode pumping, an efficiency of 1.7 dB/mW was achieved at 1.536 µm. The bending characteristics are also described. © 1990 IEEE
