<title>All-optical interconnection networks</title>

Abstract

In this paper wepresenttwoarchitectures ofhigh speedall-optical multistage interconnection networks anddiscuss how emerging opticaltechnology canprovide solution to switchingproblems which arise in telecommunication and supercomputersystems. The architectures support circuit-switched and packet-switching, and are based on all-optical bistable device which constitutes an essential component of switching units. Various design issues related to optical clock generation, its distribution, data synchronization, intensity restoration, and power requirement are also discussed.
