Optical switching networks to transport vast amounts of information are important for B-ISDN services. The wavelength division multiplexing (WDM) is emerging as the dominant technology for future optical networks. This paper proposes a large capacity photonic ATM switch architecture using WDM technology. The switch consists of two stages. The first stage is a space switch and the second stage is a wavelength switch. The proposed switch is suitable for WDM optical ATM networks, that is, an input and an output of the switch are wavelength-division-multiplexed. The switch can provide very large ATM cell switching capacity, for instance, 10Tbit/s, with reasonable complexity. The main switch module of the proposed switch has a simple architecture, and reduces the amount of a buffer hardware by introducing the WDM concept.
