A compact temperature sensor with highly germania-doped fiber (Ge-fiber)-based Michelson interferometer (MI) is proposed and experimentally demonstrated. It is constructed by splicing a 1-mm-long, 75 mol.% GeO2-doped fiber to a single-mode fiber and fabricating a taper at the splicing point. The fib...
