Abstract
A novel scheme of achieving near-ideal filter characteristics in the acoustooptic-tunable-filter (AOTF) design is proposed. When applied to bandpass filter applications, the proposed scheme should give a filter that is far superior to those from conventional designs in terms of such ideal-filter characteristics as flat-top and no side lobes that are of immense importance in the wavelength-division-multiplexing (WDM) scheme of optical-communication network systems.
