Regenerated Fiber Bragg Gratings in Multicore Fiber for Multi-parameter Sensing
[EN] Multiple regenerated fiber Bragg gratings were inscribed in all the cores of a seven-core fiber in order to develop a multi-parameter sensor designed to operate at high temperatures. We experimentally showed the possibility of measuring strains of up to 1200 mu epsilon, curvatures from 0 degree...

| Sumario: | [EN] Multiple regenerated fiber Bragg gratings were inscribed in all the cores of a seven-core fiber in order to develop a multi-parameter sensor designed to operate at high temperatures. We experimentally showed the possibility of measuring strains of up to 1200 mu epsilon, curvatures from 0 degrees to 360 degrees and temperatures up to 1000 degrees C, with a maximum curvature magnitude of at least 4.6 m(-1) and a maximum sensibility of 96 pm/m(-1). |
