Abstract

An optical modulator may include: a first semiconductor layer; a second semiconductor layer configured as a micro-disk, the second semiconductor layer being on the first semiconductor layer, and the second semiconductor layer including a first doping region and a second doping region, wherein a doping concentration of the first doping region is higher than a doping concentration of the second doping region; a first optical waveguide adjacent to the second semiconductor layer; a first electrode layer on the first doping region; and a second electrode layer on the first doping region and spaced apart from the first electrode layer, wherein the second semiconductor layer includes at least one recess, the second semiconductor layer has at least one step difference due to the at least one recess, and the first doping region, the second doping region, and the at least one recess comprise respective circular shapes, wherein all of the respective circular shapes are concentric with respect to one another.
