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

Through the efforts of many research groups and consortia over the last several years, the acousto-optic tunable filter has evolved into a device capable of high-performance wavelength-selective optical switching and wavelength routing in dense WDM s

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.

We have demonstrated a passband-flattened LiNbO/sub 3/ guided-wave acousto-optic tunable filter (AOTF). Passband flattening is achieved by approximating the predicted flattened-filter decaying-sine acoustic intensity drive function by two half cycles

This paper presents a theoretical study of the transient power fluctuations of wavelength add-drop multiplexer chains caused by the dynamic interaction of servo-controlled attenuators and saturated erbium-doped fiber amplifiers. The mechanisms respon

The recent evolution of integrated acoustooptic filters, which has been driven by the successive integration of ever more sophisticated guided-wave structures on a single X-cut lithium niobate substrate, is reviewed. The most highly integrated device

We observe power transients lasting several seconds in a reconfigurable network including cascaded channel power equalizers and chains of fiber amplifiers in a 1898 km fiber link. Gain clamping of the fiber amplifiers proves effective in suppressing
