Abstract
An optical modulator includes an optical waveguide structure extending along a first direction. The optical waveguide structure includes a first III-V compound semiconductor layer of a first conductivity type, a second III-V compound semiconductor layer of a second conductivity type, a core layer disposed between the first III-V compound semiconductor layer and the second III-V compound semiconductor layer, and a silicon-containing layer. The first III-V compound semiconductor layer is disposed between the silicon-containing layer and the core layer. The second III-V compound semiconductor layer has a width smaller than a width of the core layer.
