The system uses a 7-m-long highly doped erbium-doped fiber as the primary gain medium while two fiber Bragg gratings (FBGs) act as a wavelength selection mechanism. The sensing capability of the FBGs gives this source the possibility to be also used in a dual-sensor multiplexing scheme. The system is very stable and suitable for sensor multiplexing.4 p.application/pdfeng© 2014 Society of Photo-Optical Instrumentation Engineers (SPIE)Erbium-doped fiberFiber Bragg gratingMultiwavelength lasingSingle-longitudinal modeinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccessAcceso abierto / Sarbide irekia
