Abstract

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 width, high sensitivity requires the device contour to be close to the ray trajectory of a beam propagating through the device. Accordingly, a shaped-optimized scanner is designed so that the beam trajectory at maximum deflection is parallel to the device contour. A beam propagation method (BPM) simulation shows the performance agrees well with the analysis.
