Interferometric Single-Mode Micro-Nano Fiber Sensor 1270-2000nm

The micro-nano fiber sensor has characteristics such as compact size, flexible structure, and strong transient field. It can measure the refractive index of surrounding liquids to detect slight biochemical changes. Reported types of micro-nano fiber refractive index sensors include grating-based and resonator-based sensors. Through structural design and optimization, we have developed several interferometric micro-nano fiber refractive index sensors with advantages such as high refractive index sensitivity, low temperature sensitivity, and low manufacturing cost. Research progress in interferometric micro-nano fiber sensors includes high-birefringence micro-nano fiber ring sensors, cascaded long-period grating sensors, and micro-nano fiber interferometric sensors based on single-taper structures. By designing and optimizing the interferometer's geometric structure, we have achieved refractive index sensing sensitivity at the level of 104 nm/RIU, providing an option for the development of low-cost, highly sensitive optical biochemical sensors.
