Abstract
The recent development of photonic bandgap fibers with solid cores enables the construction of dispersion compensated all-fiber ultrashort mode-locked fiber lasers. Solid-core photonic bandgap fibers (SC-PBG) can be spliced to standard fibers with relative low loss and negligible Fresnel reflection due to the matching indexes of the cores. The fibers can provide significant anomalous dispersion with low nonlinearity and are therefore ideal for dispersion compensation in ultrafast fiber lasers. We demonstrate the use of a SC-PBG fiber for intra cavity dispersion compensation in an ytterbium based mode-locked fiber laser. The limitations on pulse duration due to the relative high third order dispersion of the SC-PBG fiber are discussed.
