Resolution considerations in electro-optic, single interface deflectors.

We discuss the maximum theoretical resolution of a single interface, electro-optically controllable beam deflector in domain-engineered LiNbO3 and report on experimental results for implementation of devices optimized either for maximum resolution or for maximum deflection angle. For the resolution optimized device we observed approximately 50 resolvable spots for a +/- 1250-V range, which to our knowledge is a report of one of the highest ratios of resolution per volt from a solid-state electro-optic beam deflector.
