Abstract

Microwave photonics is an interdisciplinary area that studies the interaction between microwave and lightwaves, for applications such as broadband wireless access networks, wireless sensors networks, radar and instrumentation. Photonic generation and processing of arbitrarily shaped microwave waveforms has been of great interest in the area of microwave photonics in recent years. Thanks to advantages of the high speed and the broad bandwidth offered by optics, photonic-assisted techniques provide the capabilities of generating and processing high-frequency and broad-bandwidth microwave arbitrary waveforms which may not be easily fulfilled by conventional electronic techniques due to the limited bandwidth. In this talk, techniques to generate and process microwave arbitrary waveforms in the optical domain using advanced fiber Bragg gratings (FBGs) are presented, with an emphasis on the system architectures in which FBGs are employed as spectral shapers and dispersive elements.
