| Popis: | In this paper, the experimental study and characterization of a novel real-time switchable multi-wavelength fiber laser has been carried out. Two different gain materials, such as a 50 km SMF and a 2.5 km DCF fibers were characterized and compared, respectively. The MWFL can generate any wavelength combination with an emission lines distance of 50, 100 and 200 GHz fitting the ITU grid specifications. By using both Er-doped fiber and Raman amplification, a ~30 nm wide lasing window at the C band can be utilized to create up to 30 different lasing wavelengths into the ITU Grid, that can be switched automatically and in real-time when desired. Utilization of such a laser for versatile interrogation of different sensing networks is also shown. This work was supported by the Spanish Government projects TEC2010-20224-C02-01, TEC2013-47264-C2-2-R, INNOCAMPUS and by the European SUDOE-Interreg Project ECOALMGT, and FEDER funds. |
