Abstract

The development of high-reflectivity photorefractive fiber gratings¹ has created a wide range of exciting new possibilities for fiber- based devices. Some applications rely solely upon the spectral filtering properties of the grating structure (e.g., their use as bandwidth limiting elements in single-frequency fiber lasers²); however in other applications, particularly those involving ultrashort optical pulses, dispersion becomes important and requires a detailed understanding.³
