Acousto-optic tunable filters (AOTF) have been investigated as a potential basis for multiwavelength cross-connects in optical networks. In this paper, we discuss crosstalk issues, some of which are common to other cross-connect technologies, and som

Use of the acousto-optic switch as a wavelength-routing element in WDM networks is described. The need for deep isolation between wavelength channels has resulted in the search for efficient sidelobe suppression techniques such as tapering of the aco

We have used a wavelength-dilated acoustooptic cross-connect, for independent routing of 8-wavelength channels separated by 2 nm. The individual acoustooptic switches making up this cross-connect provide low-crosstalk switching only for channel spaci

An acoustooptic tunable filter (AOTF) can be used as a multichannel wavelength-routing switch; however, switching efficiency decreases and the switched wavelength channels shift toward each other when neighboring channels are selected simultaneously.

Wavelength-division multiplexing (WDM) can greatly increase the connectivity of a fiber-optic network because information can be aggregated and routed on a wavelength-by-wavelength basis, by using wavelength-selective passive or active switches. In p
