摘要：

A novel scheme for multiwavelength and wavelength-switching operations in an actively mode-locked fiber laser using a cascaded sequence of fiber Bragg gratings in the laser cavity is presented. In this scheme, the cavity lengths for all wavelengths selected by the gratings are intrinsically identical, Generation of simultaneous dual-wavelength picosecond pulses with a wavelength separation of 3.5 or 20.1 nm was demonstrated. The interchange between dual- and single-wavelength operations and wavelength switching from one single-wavelength to another were simply achieved by polarization adjustment.
