Optimization of the Available Spectrum of a WDM Sensors Network Using a Mode-Locked Laser

This paper experimentally proposes a new interrogation method which consists of the combination of the information given by both domains: time and frequency. On the one hand, the sensor information is obtained in the frequency domain as usual and, on the other hand, the detection of the different pulses generated through mode locking allows the identification of each fiber Bragg grating (FBG). It ...
