Thermo-optic characterization of optically similar aqueous solutions using SMS/MMI fiber sensor
Multimode interference (MMI) fiber sensors with singlemode–multimode–singlemode (SMS) structures based on no-core multimode fiber (NC-MMF), have been widely employed for refractive index (RI) sensing of liquid samples due to their simplicity, low cost, and high sensitivity to changes in the immersion medium. In this wo...
