Paper Abstract

Acousto-optic tunable filter (AOTF), acousto-optic switch (AOS) and acousto-optic equalizer with high acousto-optic interaction efficiency are important in WDM networks. The technologies of unidirectional and focused transducer were adopted for the design of integrated acousto-optic device. Extensive usage for the acousto-optic device such as optical switches, gain equalizer and optical add-drop multiplexer have been studied. The concept that changing the radius of focus transducer can adjust the switching speed and FWHM of the filter was proposed for the first time.
