【摘要】 用速率方程研究了稀土掺杂聚合物光纤的团簇现象,提出了团簇化铕离子相互作用的理论模型,并以该模型为基础,通过速率方程得到光纤透射率T随泵浦功率P变化关系,理论上分析了团簇化离子百分比ρ以及团簇化离子之间相互作用时间τ对光纤透射率T的影响.更多还原

【Abstract】 In this paper,the clusters in rare earth doped polymer optical fibers were studied.The cross relaxation model of clustering Eu3+ ions was described,the relationship between transmission T and launch power P was obtained by rate equation based on the above model.The effect of percentage of clusters ρ and the time of cross relaxation τ to transmission were analyzed theoretically.更多还原
