Abstract

A data center (DC) is one of the main building blocks of modern information technology. 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) receiver with detector array. The proposed receiver is described in detail, a numerical example is given, and alternate options for its construction are explored. For a given set of parameters we found that a three ring detector with optimized ring area is comparable to seven ring evenly spaced detector.
