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 HE11x and HE11y 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 X 10(-5) RIU ( refractive index units) for HE11x modes and 6 X 10(-5) RIU for HE11y modes, whereas 3 X 10(-5) RIU for HE11x modes and 4 X 10(-5) RIU for HE11y modes are demonstrated for the amplitude interrogation.
