In this paper, the theoretical study of a new electrooptic tunable filter based on TE–TM mode conversion, and the high form birefringence that occurs in a GaAs/AlAs multiquantum-well waveguide is presented. Then TE–TM conversion can be achieved with a relatively low voltage (30 V). Such a filter shows off a tuning rate voltage ranging around 7 V/channel, and as regards selectivity a 1.3 nm filter bandwidth can be obtained.
