Abstract

A numerical analysis of a novel birefringent photonic crystal fiber (PCF) biosensor constructed on the surface plasmon resonance (SPR) model is presented in this paper. This biosensor configuration utilizes circular air holes to introduce birefringence into the structure. This PCF biosensor model shows promise in the area of multiple detection using HE^x₁₁ and HE^y₁₁ modes to sense more than one analyte. A numerical study of the biosensor is performed in two interrogation modes: amplitude and wavelength. Sensor resolution values with spectral interrogation yielded 5 × 10^-5 RIU (refractive index units) for HE^x₁₁ modes and 6 × 10^-5 RIU for HE^y₁₁ modes, whereas 3 × 10^-5 RIU for HE^x₁₁ modes and 4 × 10^-5 RIU for HE^y₁₁ modes are demonstrated for the amplitude interrogation.
