摘要:
提出涂覆单层石墨烯的电介质纳米盘结构,并利用有限元方法数值解析这种纳米结构的表面等离子激元回音壁模的电磁场特性.计算并分析品质因子(Q值)、模式体积随着电介质纳米盘半径大小、石墨烯化学势和谐振频率的变化规律.结果表明:当纳米盘的半径为5 nm,石墨烯化学势为0.9 eV时,其品质因子高达195,对应模式体积小于2×10-7(λ0/2n)3.
Abstract:
Graphene monolayer covered dielectric nanodisks are proposed in this paper. The surface plasmonic polariton whispering-gallery mode electromagnetic field properties of the proposed nano structures are numerically investigated by using finite element method. The quality factor, mode volume and Purcell factor of the optical modes are calculated as a function of dielectric nanodisks radius size, chemical potential of graphene and resonant frequency. Calculation results showed that a quality factor as high as 195, and a mode volume of less than 2×10-7(λ0/2n)3 is achieved in a dielectric nanodisk with radius of 5 nm, where the chemical potential is 0.9 eV.
