Abstract

In this paper, we proposed a sensor based on the measurement of the first Stokes parameter of the transmitted signal by a short length PM-FBG. Since it is important to characterize the polarization properties of PM-FBG for a lot of applications, we also present theoretical and experimental studies of the reflected and transmitted Stokes parameters. Experimental evolutions are obtained with a PM-FBG by means of a tunable laser source and a polarimeter. It is concluded that the technique is compatible with frequency multiplexing and can be used in the case of quasi-distributed sensors.
