Abstract
fs-point-by-point through the coating written FBGs as a basis for novel sensor concepts using 25µm optical fiber. fs-point-by-point FBGs in novel single mode fiber with a cladding diameter of 25µm have been produced in fiber that is 5 times smaller than conventional telecommunication optical fiber. The development opens the path to new sensor types including miniature pressure sensors with a diameter of only 330µm (1Fr.)
