Passive optical network architecture based on waveguide gratingrouting

摘要

We explore an optical network architecture which employs densenwavelength division multiplexing (WDM) technology and passive waveguidengrating routers (WGRs) to establish a virtual topology based onnlightpath communication. We examine the motivation and the technicalnchallenges involved in this approach, propose and examine thencharacteristics of a network design algorithm, and provide somenillustrative performance results
