In this research work, we design a biosensor using a six-fold photonic quasi-crystal fiber with a fan-shaped analyte channel based on surface plasmon resonance (SPR). We numerically analyze both the dispersion relations and loss spectra for three different refractive indices of the analyte, na, using finite element method. Through optimization of the structure, we find that the proposed biosensor exhibits a maximum refractive index sensitivity of 3200 nm/RIU and a resolution of 3.12 × 10−5 RIU when na is increased from 1.41 to 1.43. We infer that the coupling between the core mode and SPR mode can be explained as a complete coupling of the loss matching condition or an incomplete coupling of the phase matching condition. Owing to the ease of fabrication of the proposed biosensor with an average sensitivity of 2250 nm/RIU, we envisage that this biosensor could turn out to be a versatile instrument for detecting the biomolecules.
