Abstract

We present and numerically characterize a single liquid-core photonic crystal fiber (PCF) based surface plasmon resonance (SPR) sensor. The two gold coated liquid analyte channels as big as core are placed near the core for easy excitation of free electrons to produce surface plasmon waves (SPWs). A sufficiently strong SPR is achieved by adjusting the size of the air holes between the core and the liquid analyte channels. The maximum positive refractive index (RI) sensitivity of3800nm/RIU is achieved in the sensing range of 1.45–1.46. The sensor shows a negative RI sensitivity once the RI of the analyte is greater than 1.5.
