Abstract

An exciting recent development in fiber optic technology is the ability to imprint diffraction gratings directly into the core of an optical fiber through ultraviolet photosensitivity.¹ It is expected that fiber gratings will play a major role in the next generation of optical communications systems, including single-wavelength, wavelength-division- multiplexed (WDM), and soliton transmission systems. Fiber gratings and related devices will impact nearly every aspect of these systems, from sources to optical amplifiers to receivers. In this talk we report recent progress on a number of optical communications applications based on fiber gratings.
