Abstract

Surface plasmon resonance (SPR) sensors have been widely used in refractive index related measurements, including label-free bio-chemical sensing, because of their high sensitivity and real-time detection capability. It is well established that noble metals, in particular, gold (Au) and silver (Ag), support plasmon resonances that can be tuned throughout the UV-vis-NIR region. However, the plasmonic properties of Cu have not received much attention as compared to Au and Ag because of oxidation of the Cu surfaces. This work investigates the optical properties of Cu nanoparticles deposited on a tilted fiber Bragg grating (TFBG) by pulsed chemical vapor deposition (P-CVD). The effect of oxidation on the SPR properties of the Cu nanoparticles coated TFBGs was further studied.
