Lopez-Higuera, 'Stability Comparison of Two Ring Resonator Structures for Multiwavelength Fiber Lasers Using Highly Doped Er-Fibers,' in Journal of Lightwave Technology, vol. 27, no. 14, pp. 2563-2569, July15, 2009.0733-872410.1109/JLT.2008.2011820https://academica-e.unavarra.es/handle/2454/35953An experimental comparison of stability between two different fiber laser topologies is carried out. The lasers are based on ring resonators that include highly-doped Er-fibers. Both topologies use fiber Bragg grating reflectors in order to select the emission wavelengths. The experimental results confirms that the novel topology based on fiber optic circulators arranged in an hybrid serial-parallel configuration offers a better stability and higher optical signal to noise ratios (OSNR) than the simpler based on a parallel configuration.7 p.application/pdfeng© 2009 IEEE.
