We report the design and demonstration of a novel narrow-linewidth fiber laser that is switchable (at microsecond speeds) to precise predesignated wavelengths. This simple multiwavelength source, based on off-the-shelf components (fiber Bragg gratings (FBGs) and fiber Fabry-Perot filters), appears very promising for wavelength-division multiplexing.
