Single-Mode-Multimode-Single-Mode Optical Fiber Sensing Structure With Quasi-Two-Mode Fibers.
IEEE Transactions on Instrumentation and Measurement(2018)
摘要
This paper reviews some aspects of optical fiber sensors based on a single-mode (SM)-multimode (MM)-SM structure and reports on the realization of temperature sensors in which the MM section is made by a quasi-two mode fiber. Two different realizations are compared that rely on: 1) a bend-insensitive fiber operated in the second optical communication window and 2) an SM fiber at 2 μm operated in t...
