摘要:

我们用频域模型求解了光在嵌入非线性可饱和增益材料的负折射率材料中的传播方程。我们表明,可用的增益材料可以导致完全的损失补偿,只有当它们位于该区域的场增强是最大的。我们研究了增益复合材料以及金属夹杂物中的场的增强,并分析表明,有效增益是由平均近场增强。

英文摘要:

We solve the equations governing light propagation in a negative-index material with embedded nonlinearly saturable gain material using a frequency-domain model. We show that available gain materials can lead to complete loss compensation only if they are located in the regions where the field enhancement is maximal. We study the increased enhancement of the fields in the gain composite as well as in the metal inclusions and show analytically that the effective gain is determined by the average near-field enhancement.
