Paper Abstract

In this paper recent theoretical and experimental work in the area of multiple quantum well modulators is presented. The theoretical work includes the application of the effective mass approximation to compositional MQW structures and the use of a two-band tight-binding approximation to doping modulated Nipi structures. The theoretical calculations are used to obtain electric-field-dependent absorption and refractive index in the above MQW structures. Experimental electroabsorption in compositional MQW structures is described, as well as preliminary optical characterization of Nipi structures. Concepts of photoactivated and electrically addressed MQW-spatial light modulators are presented. Finally, theoretical evaluation of quantum dot arrays and their potential use in spatial light modulators is discussed.
