This paper presents the analysis of a general nonrectangular electrooptic (
EO) scanner and compare its performance to a rectangular device. Since the
scanning sensitivity of an EO scanner is inversely proportional to its widt
h, high sensitivity requires the device contour to be close to the ray traj
ectory of a beam propagating through the device, Accordingly, a shaped-opti
mized scanner is designed so that the beam trajectory at maximum deflection
is parallel to the device contour, A beam propagation method (BPM) simulat
ion shows the performance agrees well with the analysis.
