Enhancement of SPR-sensor sensitivity in garnet-based plasmonic heterostructures

We propose a novel approach to the enhancement of the SPR-sensors sensitivity via utilization of the specially designed garnet-based magnetoplasmonic heterostructures with one-dimensional photonic crystals. Excitation of the long-range propagating modes in such structures as well as the magnetooptical measurements instead of reflection ones make the investigated resonances extremely narrow thus significantly increasing the SPR sensor sensitivity.
