Paper Abstract

A pigtailed DFB source operating at 1520 NM feeds an all-fiber interferometric scheme to obtain absolute measurements. The frequency modulation of the source is in-line controlled by means of an all-fiber ring resonator. The sensor was realized by all-fiber components and it was designed with a multisensing capability. The extremely narrow emitting-line of the DFB enphasizes the resolution features of the scheme. The precision figure is also reported on the basis of the first experiniental data.
