Paper Abstract

Operation of an underwater acoustical pressure transducer using an active Fiber Bragg Grating (FBG) attached to a profiled membrane is described. Presented results of Finite Element modeling of the transducer show strain gradients acting on the FBG. A model of passive FBG and DFB fiber laser was developed using coupled-mode method. Using a program based on that model, the effect of strain gradients on the operation of presented sensor was investigated.
