Abstract :
A plasmonic sensor based on nanopatch photonic crystal slab was proposed. The sizes of the nanopatch was optimized. With shallow etched and small size of the nanopatch, the sensor achieves simultaneously a high sensing performance of FOM=171.6 RIU-1 and a clear registration of FH/FWHM=0.261 for the lattice constant of P=750. The results of P=1000 and P=1250 are also presented.
