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 of a sine wave of successively lower intensity. These filters have a cross-state 3-dB passband of /spl sim/1… CONTINUE READING
