Abstract

Wavelength-selective circuit and packet switching applications of acoustooptic tunable filters (AOTFs) in wavelength-division multiplexing (WDM) networks are discussed. For circuit switching applications, the AOTFs are used as 1×2 or 2×2 wavelength-selective space-division switches. It is shown how large switches can be built from these basic building blocks both schematically and physically. Such switch fabric can be used for routing and cross connect between central offices. For packet switching applications, the AOTFs are used as wavelength-tunable receivers in a broadcast and select cross-connect configuration. It is shown how such a configuration can accomplish packet communication with high throughput. Various system issues are also discussed
