Receiver design for OWC orbital angular momentum communication in data center applications

A data center (DC) is one of the main building blocks of the internet. Any intra DC network should strive to achieve high throughput, while continuing to be flexible in responding to changing traffic patterns. Optical wireless communication links on top of the fiber/wire infrastructure could offer flexible and dynamic reconfiguration of the network. In this paper we present the design of an optical wireless communication orbital angular momentum (OAM) system which could provide faster communication rate. The proposed receiver is described in detail and a numerical example is given.
