提出了一种用活性材料填充的等离子体激元腔来解释光开关。数值研究了该器件的光学特性，包括透射率、响应时间和开/关态的场分布。我们证明了这种增益辅助的等离子体结构可以在纳米区域实现光开关，并将开关时间缩短到亚皮秒水平。我们的研究结果表明，该结构在光通信和光子集成电路的潜在应用。
A plasmonic cavity filled with active material is proposed to explain optical switching. Optical properties, including transmission, response time, and field distribution of on/off state, are numerically investigated. We demonstrate that such a gain-assisted plasmonic structure can achieve optical switching in the nanodomain and shorten the switching time to the subpicosecond level. Our results indicate the potential application of the proposed structure in optical communication and photonic integrated circuits.
