摘要：

A surface plasmon resonance（SPR） sensor with a high-order absentee layer on the top of metallic film is proposed.The performance of the SPR sensor with NaCl, MgO, TiO;or AlAs high-order absentee layer is analyzed theoretically. The results indicate that the sensitivity and the full width at half maximum of those SPR sensors decrease with the increasing of the order of absentee layer, but the variation of the figure of merit（FOM） depends on the refractive index of absentee layer.By improving the order of absentee layer with high-refractive-index, the FOM of the SPR sensor can be enhanced. The maximum value of FOM for the SPR sensor with high-order TiO;（or AlAs） absentee layer is 1.059%（or 2.587%） higher than the one with one-order absentee layer. It is believed the proposed SPR sensor with high-order absentee layer will be helpful for developing the high-performance SPR sensors.
