摘要：

Lateral transport in electro-optic spatial light modulators with vertical electric field geometries is one of the primary causes of reduced resolution in electro-optic spatial light modulators. In this paper, we analyze the role of lateral drift caused by fringing space-charge fields. An analytic expression for the modulation depth of space-charge screening fields is derived self-consistently within the small-amplitude approximation. The lateral drift causes the device resolution to be electric-field dependent, with decreasing resolution for larger applied field strengths. The spatial resolution of photorefractive quantum well devices operating in the quantum-confined Stark geometry is discussed within this context.
