Abstract :
Plasmons on the surface of large metalized holes containing analyte are excited by the fundamental mode of a microstructured fiber. Phase matching between Plasmon and core modes is facilitated by the perforation of fiber core. A comparison of Au and Ag metalized layer is illustrated. There are some differences between gold and silver layer in SPR excitation ability, strength, and sensitivity.
