Abstract
We compare the characteristics of three electroabsorption modulators fabricated using GaAs/AlGaAs multiple quantum well structures with well widths 47, 87, and 145 Å. We find that the narrow well structure provides the largest change in transmission. The 87 Å well structure provides the largest contrast ratio, while the wide well sample offers the lowest operating voltage.Keywords
