Electroabsorption Transceiver (EAT): Device Concepts and System Applications

摘要

Recently, lightware systems have attracted great interest not only for digital optical communication but also for the distribution of microwave and mm-wave signals in wireless applications. Future wireless communication networks are expected to offer broadband multimedia services to a large number of subscribers. As a consequence, the radio frequency is expected to be within the mm-wave band where a sufficient bandwidth for the large number of broadband channels is available. Since the electrical transmission of the mm-wave radio signals over long distances is not feasible, fiber-wireless systems have attracted great interest. They are considered to form the backbone of future broadband mm wave wireless communication systems. Obviously, the successful implementation of mm-wave wireless communication networks in mass-market applications strongly depends on the costs of the infrastructure. In that respect, specially the cost of each single base station (BS) is a very critical factor since future wireless networks are expected to support a large number of remote BSs. Consequently, it is of great interest to reduce the base station complexity and cost.
