This research presents a novel square-shaped photonic crystal fiber (PCF)-based surface plasmon resonance (SPR) sensor, designed using the external metal deposition (EMD) technique, for highly sensitive refractive index (RI) sensing applications. The proposed sensor operates effectively over an RI range of 1.33 to 1.37 and supports both x- polarized y-polarized modes. It achieves wavelength sensitivity 15,800 nm/RIU 14,300 nm/RIU, amplitude sensitivities 11,584 RIU−1 11,007 RIU−1, respectively, x-pol. y-pol. also reports resolution in order 10−6 RIU strong linearity R2 ≈ 0.97 polarization modes, indicating its potential precision detection complex environments. Beyond sensor’s structural performance innovations, this work explores future integration artificial intelligence (AI) into PCF-SPR design. AI techniques such as machine learning deep offer new pathways calibration, material optimization, real-time adaptability, significantly enhancing reliability. convergence with not only opens doors smart, self-calibrating platforms but establishes foundation next-generation sensors capable operating dynamic remote
