Historically, data transmission through multimode fibers has not been popular due to the modal crosstalk and complexity involved in signal processing. However, over the past few years, due to the exponential growth in IP traffic, the capacity of single-mode fiber based systems is approaching the fundamental non-linear Shannon limit. Therefore, there is renewed interest in multimode systems, devices and fibers to boost capacity beyond the single-mode nonlinear limitation. Central to the realization of future high capacity optical networks is the development of advanced multimode fibers, multicore fibers, as well as new devices to enable scalable, low-loss schemes for unlocking fiber capacity. On the other hand, this resurgence of interest in multimode fiber systems is providing a rich platform for exploring complex multimode nonlinear dynamics. In this seminar, I will present recent advances in multimode fibers and fiber devices, highlighting their application to tailoring the properties of multimode optical fiber systems.
Rodrigo Amezcua received his PhD in 2008 from the Optoelectronics Research Centre at the University of Southampton, under the supervision of Prof. David Richardson. From 2007-2009 he was a post-doctoral researcher at the University of Bath with Prof. Jonathan Knight. Prior to joining CREOL UCF, he was a Laser Development Engineer with Powerlase Photonics (2009-2011) in the UK. Since 2011, he has been with CREOL as a Research Assistant Professor and Assistant Professor. At CREOL he leads the Micro-structured Optical Fiber and Devices Laboratory. His research interests are in the development of optical fibers and fiber devices for guiding, generating and controlling light in new ways.
