摘要:A cascaded string of six intrinsic Fabry-Perot Interferometer sensors was fabricated inside a silica fiber for high-temperature sensing using ultrafast laser direct writing. These sensors were interrogated by the fast white-light interferometer demodulation in real-time, yielding a temperature sensitivity between 4.4-13.4nm/degrees C for up to 800 degrees C at a spatial resolution of 1-cm.
