摘要： The invention relates to a method and a device for producing at least one fiber Bragg grating in a waveguide, wherein the waveguide has at least one core having a first refractive index and the fiber Bragg grating contains a plurality of spatial regions which each occupy a partial volume of the core and have a second refractive index, wherein the spatial regions are each produced by the action of laser radiation on a partial volume of the core, wherein the laser radiation contains a plurality of pulse trains each containing a plurality of individual pulses, wherein the time interval between successive individual pulses is smaller than the time interval between successive pulse trains and the time interval between successive individual pulses is chosen between 10 ns and 100 ps or the pulse train has a duration of 50 fs to 50 ps.

摘要： The invention relates to a fibre-optic sensor comprising an optical waveguide having at least one first core and a cladding surrounding the first core, wherein the first core extends substantially over the entire length of the optical waveguide, wherein the sensor has at least one second core which is at least partly surrounded by the cladding, wherein the longitudinal extent of the second core is less than the total length of the optical waveguide and at least one Bragg grating is introduced into the second core. Furthermore, the invention relates to a use of the fibre-optic sensor.
