Abstract:We experimentally demonstrated an all fiber loading sensor system based on a 45°-and an 81°-tilted fiber grating (TFG). We have fabricated TFGs with tilted structures at 45° and 81° consecutively in one fiber. When the transverse load applied to the 81º-TFG, the light coupling to the two orthogonally polarized peaks will interchange from each other, which provides a solution to measure the load. We further investigated the all fiber loading sensor system using a single wavelength source and a power meter. The … Show more
