Abstract
Abstract
A cascaded string of six intrinsic Fabry-Perot Interferometer sensors was fabricated inside a silica fiber using ultrafast laser direct writing, then interrogated by fast white-light interferometer demodulation. Temperature sensitivity between 4.4-13.4nm/0C for up to 8000C at a spatial resolution of 1-cm was acquired.
