We proposed a novel waveguide structure for electroabsorption modulator. By selective undercut etching the active region, the doped conducting layers can be separated. The calculation shows that it has the properties of lower microwave loss, higher microwave speed and higher optical coupling efficiency compared with conventional ridge type.
