Speech Title: All-optical signal processing with fiber Bragg gratings

Abstract: Optical fiber Bragg gratings have received lots of research and application interests in past twenty years. They are refractive index modulation structures created inside optical fiber with laser inscription technology. They are fully compatible with optical fiber systems and have low insertion losses. Optical fiber Bragg gratings can be designed to be various optical filters with different spectral profiles and dispersion profiles, thus can be used to process optical signals directly in optical fiber. In this paper, we will review our past and recent research work on optical fiber Bragg gratings and discuss their applications in all-optical signal processing.
