Description/Abstract
We report significant advances in the development of simple all-fiber, tunable acousto-optic spectral filters based on null couplers. Close to ideal device performance characteristics have been obtained for the first time through improved control of the coupler uniformity. Furthermore, using a double pass arrangement, we demonstrate filter bandwidth reduction and improved side-lobe suppression of -20dB. The double pass configuration is also shown to double the frequency shifts obtainable from such devices
