Abstract

Microwave and mm-wave photonics for broadband communications is an area of important growth and of great interest for information society technologies (Internet traffic, video on demand, >1 Gb/s to the home, 40 Gb/s optical systems, optical beam forming for intelligent antennas, all-optical networks, etc.). Fiber Bragg gratings are key components for the development of low-cost microwave photonics. Reliability and high tunability capacity are some of the specific advantages of using fiber Bragg gratings. Recent developments include novel configurations to obtain tunable all-optical negative multi-tap microwave filters, adjustable dispersion devices and temperature insensitive transversal filters.
