Abstract : Surface-normal optical modulators based on III-V semiconductor quantum wells (QWs) and superlattices (SLs) are important for potential applications such as two-dimensional arrays for optical interconnection and optical processing. Asymmetric Fabry-Perot (ASFP) structures utilizing electroabsorption effects of either QWs or SLs inside the cavities sandwiched by a pair of asymmetric mirrors (with bottom mirror more reflective) have been implemented with high contrast ratios. Depending on the active medium and the ASFP configuration, the ASFP can be either normally-on or normally-off.
