Paper Abstract

A new concept of optical fiber dynamic strain sensor has been theoretically studied and its proof-of-the-principle experimentally demonstrated. It is based on two wave mixing by gain saturation in an optically pumped erbium doped optical fiber. The main feature of this sensor is insensitivity to slow varying perturbations, which is of major interest for underwater acoustic applications for instance.
