“…Multimode optical fibers with tapered structures have garnered attention in the sensing field for their high sensitivity and robust durability. By depositing a metal layer on the surface, the tapered structure can be adjusted to enhance measurement sensitivity [17], particularly exhibiting strong responses to variations in the vertical direction [18], making them suitable for various environmental monitoring applications [19,20]. Fiber Bragg Grating (FBG) utilizes the diffraction principle to modulate the refractive index (RI) of the optical fiber periodically, forming a diffraction grating with high sensitivity and frequency selectivity, suitable for precise measurements of parameters for instance temperature and stress [21,22].…”
