摘要：

Surface plasmon resonance in super-period metal nanoslits can be observed in the first order diffraction as well in the zeroth order transmission. In this paper, surface plasmon resonance modes in various super-period gold nanoslit arrays are investigated. It is found that the surface plasmon resonance frequencies are determined by the small period of the nanoslits in the super-period nanoslit unit cell. The number of nanoslits in the unit cell and the nanoslit width do not control the surface plasmon resonance frequencies. It is also found that the resonance frequency observed in the first order diffraction reveals more accurately the surface plasmon resonance frequency in the super-period metal nanoslit device.
