The device makes use of a tunable Yb-doped fiber laser, a cascade of Fiber Bragg Grating mirrors, and a concatenation of standard silica fibers with stepwise decreasing dispersion. It is shown that the dispersion-decreasing-fiber set enhances the width of the generated SC, since it favors the fission of the CW input into high-order solitons. The generated SC spans from 1280 to 1513 nm, shows an average output power of 1.34 W, and exhibits > 0-dBm/nm spectral density of over 200 nm PB IEEE SN 0733-8724 YR 2007 FD 2007-08 LK http://hdl.handle.net/10017/28498 UL http://hdl.handle.net/10017/28498 LA eng NO Ministerio de Educación y Ciencia DS MINDS@UW RD 26-abr-2024
