Summary: This study designs a gold and silver coated multi-channel photonic crystal fiber based surface plasmon resonance sensor structure for simultaneous detection of a wide range of refractive indices. Bending analysis and sensitivity performance evaluation show that bending enhances the sensitivity of the y-polarized mode while the x-polarized mode remains almost unchanged. Spectral analysis further demonstrates that the sensitivity performance of the bent structure can be improved up to 50% by bending. This proposed structure is capable of detecting analytes between 1.33-1.36 RIs and has great potential in biomedical and biochemical applications.
