Photonic Ring and Bus Networks with Reduced Station Hardware

Recent advances in photonic amplification have re-motivated the use of ring and bus topologies in single-hop wavelength division-multiplexed (WDM) networks [1]. The use of WDM offers a significant increase in capacity over traditional single-channel networks. However, the parallel channel nature of these networks tends to complicate both the media access protocols and hardware requirements of the user stations, [1] and [2]. In this paper, four …
