N2 - In this work, the recent work on fabricating harsh environment fiber grating by femtosecond laser and applications as multi-parameter sensor is reported. Bragg gratings have been written in single mode (SM), multimode (MM) silica fiber, polarization maintaining (FM) single mode silica fiber, and highly multimode 60-micron thinned sapphire fiber. Silica gratings can survive in temperature higher than 1000 Celsius degree. And sapphire fiber grating can even go as high as 2000 Celsius degree. Multiple parameter integrated fiber sensor that can detect vector bending and ambient temperature simultaneously with a single asymmetric fiber Bragg grating is realized in MM silica fiber and PM silica fiber. Higher order modes of sapphire Bragg grating is filtered out by mode winding to realize single mode operation.
