Abstract :
A study of the application of InGaAs/GaAs multiquantum wells for modulators using the electroabsorption ( Delta alpha ) and the electrofraction ( Delta n) effects is presented. The important parameters for these devices were measured directly in both waveguide and surface-normal configurations. The Delta n and Delta alpha spectra were shown to satisfy the Kramers-Kronig relations.
