摘要：
Ahighly sensitive photonic crystal fiber-based hemoglobin sensor is numerically simulated and studied. Variations of the fundamental mode loss and dependent sensitivities (wavelength and amplitude) are analyzed in the reference of gold layer thickness, lattice period, cladding air holes size, and different analyte refractive indices. This sensor structure offers the highest amplitude sensitivity of 2080 RIU−1 with a resolution of 4.80 × 10−6 RIU at a hemoglobin refractive index of 1.38. Additionally, this sensor can be fabricated in the length of millimeter with high-quality factor of 239. This amended surface plasmon resonance-based sensor might be suitable for recognizing diseases related to a blood disorder. © 2021 Elsevier Ltd
