Abstract: (1495 Views)
In this work, a refractive index (RI) sensor based on a Multimode–Single-mode–Multimode (MSM) fiber structure is fabricated. Due to the core mismatch of the two types of fibers, the sensor becomes sensitive to the RI of the outer media. The performance of the sensor is characterized inside water-glycerol solutions with different RIs. The maximum sensitivity of the sensor in the RI range of 1.44-1.475 is at the wavelength of 1400nm and equals to -18.144 RIU-1. Facile fabrication and low cost are two of the main advantages of the fabricated sensor.
