In this paper, we study the design of regular multicast networks implemented with optical passive star (OPS) couplers. We focus on an architecture based on both Kautz graphs and stack-graphs, and show that it is very cost-effective with respect to its resources requirements, namely the number of OPS couplers, power budget, scalability and number of transceivers, and presents a large ratio number-of-nodes/diameter. The important issue of medium access control is also addressed and control protocol for accessing the optical couplers are given and analyzed. Finally, we show through simulation that these control protocols efficiently implement shortest path routing on these networks
