Ultrasensitive tapered optical fiber refractive index glucose sensor
Scientific Reports, 2023 Refractive index (RI) sensors are of great interest for label-free optical biosensing. A tapered optical fiber (TOF) RI sensor with micron-sized waist diameters can dramatically enhance sensor sensitivity by reducing the mode volume over a long distance.
