【摘要】 以P2O5、Nb2O5、Na2O、Ga2O3和PbCl2为基质制备Er3+/Yb3+共掺磷酸盐(EYPNGP)玻璃.应用McCumber原理研究的结果显示,EYPNGP玻璃在1530 nm处的峰值受激发射截面和有效带宽分别为6.20×10-21cm2和56.6 nm,大于常规的掺铒磷酸盐玻璃.数值模拟计算结果表明,对于EYPNGP光纤放大器而言,利用较短的激活长度就可获得足够的信号光放大.更多还原

【Abstract】 Er³⁺/Yb³⁺ co-doped lead niobium-phosphate glass（EYPNGP） was prepared,whose host compositions are P₂O₅、Nb₂O₅、Na₂O、Ga₂O₃ and PbCl₂.The results analyzed by McCumber theory show that the peak stimulated emission cross section value and the effective bandwidth value of EYPNGP glass around 1530 nm are 6.2010^-21 cm² and 56.6 nm,respectively,they are larger and broader than traditional phosphate glasses.As for the EYPNGP optical fiber amplifier,the results of numerical simulation show that large amplified signals can be obtained with a shorter length of fiber.更多还原
