Abstract :
We report on a new class of plasmonic nanosensor which combines extraordinary optical transmission and resonance within structural defects in a plasmonic crystal. Resonant modes within the defect increase plasmon wave lifetime leading to enhanced light-analyte interactions. Initial sensitivity characterization was performed and simple linear regression analysis determines sensitivity to be 501nm·RIU-1, showing improvement over traditional nanohole array sensors.
