Abstract:  Optical fiber transmission systems constitute the backbone of the global communications infrastructure. Space-Division Multiplexing (SDM) has been proposed in recent years to overcome capacity limitations and increase efficiency of current single-mode fiber-based transmission systems. In SDM transmission systems, optical fibers are employed that allow for transmission of independent signals at the same wavelength through different spatial channels. Promising SDM fibers include few- or multi-mode fibers (FMF or MMF), where a single fiber core guides a finite number of modes and multi-core fibers (MCF), where several fiber cores are arranged inside one cladding, each supporting a single (single-mode MCF) or several fiber modes (few-mode MCFs). In this talk we will describe the characteristics of such fibers and a range of transmission experiments exploring their suitability for high-capacity optical transmission systems and discuss how amplifiers exploiting the spatial domain may be key components to facilitate successful commercial deployment of SDM technology. We will further discuss network scenarios than can exploit the spatial domain for enhanced transmission performance.

Biography:  Georg Rademacher received the Dipl.-Ing. and Dr.-Ing. degree in electrical engineering from Technische Universität Berlin, Germany, in 2011 and 2015, respectively. During his doctoral studies, he did internships at Bell Laboratories in Holmdel, USA and the National Institute of Information and Communications Technology (NICT) in Japan. In 2016 he joined the photonic network system laboratory at NICT in Tokyo, Japan, where he is engaged in research on high capacity optical transmission systems.
