Maxwell鱼眼微球透镜在光纤系统中的耦合效率极限

Coupling Efficiency Limit of Maxwell's Fish Eye Microball Lens

本文用梯度折射率（ＧＲＩＮ）介质的光线理论分析了Ｍａｘｗｅｌｌ鱼眼微球透镜光学耦合系统的耦合效率，得到了单、双透镜耦合系统耦合效率极限的计算公式。严格的数值计算表明，Ｍａｘｗｅｌｌ鱼眼微球透镜耦合系统的耦合效率远高于普通的均匀介质球光学耦合系统。

Using the theory of ray in gradient index medium, coupling efficiency of Maxwell's fish eye microball lens is analysed, calculating coupling efficiency limit formula of a single or double 'fish eye' lens and ordinary ball lens. The results by the rigorous numerical method shows that coupling efficiency of a single fish eye microball lens is more than that of ordinary microball lens by 40￣ 50 per cent in the suitable parametes, even it is equal to double ordinary microball lens. And the coupling efficiency of two 'fish eye' lens is more than that of two ordinary microball lens by 5￣10 per cent in the coupling efficiency.
