摘要:

从理论上研究了金属纳米粒子(MNP)和半导体量子点(SQD)组成的混合纳米系统的粒子数动力学和吸收光谱。我们研究了激子-等离子体激元耦合对纳米结构的粒子数动力学和吸收特性的影响。我们的研究结果表明,由于激子-等离子体激元耦合,杂化纳米系统的非线性光学响应可以大大增强或降低。所得结果可能在光开关等纳米光学器件和单光子晶体管等量子器件中具有潜在的应用价值。

英文摘要:

We studied theoretically the population dynamics and the absorption spectrum of hybrid nanosystem consisted of a matal nanoparticle (MNP) and a semiconductor quantum dot(SQD). We investigated the exciton-plasmon coupling effects on the population dynamics and the absorption properties of the nanostructure. Our results show that the nonlinear optical response of the hybrid nanosystem can be greatly enhanced or depressed due to the exciton-plasmon couplings. The results obtained here may have the potential applications of nanoscale optical devices such as optical switches and quantum devices such as a single photon transistor.
