Lopez-Amo, 'Narrow-Linewidth Multi-Wavelength Random Distributed Feedback Laser,' in Journal of Lightwave Technology, vol. 33, no. 17, pp. 3591-3596, 1 Sept.1, 2015.0733-872410.1109/JLT.2015.2445377https://academica-e.unavarra.es/handle/2454/35959In this work, narrow-band emission lines are generated by means of two random distributed feedback fiber laser schemes. Spectral line-widths as narrow as 3.2 pm have been measured, which significantly improves previous reported results. The laser is analyzed with the aim of obtaining a spectral line-width as narrow as possible. Additionally a variation of this setup for multi-wavelength operation is also validated. Both schemes present a simple topology that use a combination of phase-shifted fiber Bragg gratings and regular fiber Bragg gratings as filtering elements.6 p.application/pdfeng© 2015 IEEE.
