基于一维随机硅光栅的石墨烯表面等离子体安德森局域
|
摘要
提出了一种中红外波段下探究表面等离子体在石墨烯与硅光栅混合结构中传输安德森局域的方法.在石墨烯片下设计一维随机硅光栅结构来实现石墨烯表面等离子体随机硅光栅.通过调节石墨烯的费米能级来改变由硅光栅的无序引起的石墨烯表面等离子体安德森局域的共振波长.当费米能级是0.6eV时,局域石墨烯表面等离子体在随机硅光栅结构中的场强强度比在周期性硅光栅结构中大70倍.该结构有望应用于可调集成滤波器,宽带调制器以及等离子体传感器等.
A novel method was investigated to achieve in-plane graphene surface plasmon anderson localization in mid-infrared region by transferring agraphene sheet on the one-dimensional random silicon gratings.By adjusting the Fermi level of graphene,the resonance wavelengths of anderson localizated graphene surface plasmon caused by its random nature can be easily tuned.The field intenstiy of localizated graphene surface plasmon is higher than the corresponding one in the periodic silicon gratings70 times when the Fermi level is set to be 0.6 eV.The structure proposed can be appiled to the tunable integrated filters,broadband modulators and plasmonic sensors.
