Abstract
According to embodiments of the present invention, an optical modulator is provided. The optical modulator includes a substrate, and a waveguiding arrangement on the substrate, the waveguiding arrangement having a waveguide, and at least one graphene layer arranged to interact with light propagating in the waveguiding arrangement, wherein the waveguide is designed such that the light interacting with the at least one graphene layer has a maximum intensity overlapping with the at least one graphene layer. According to further embodiments of the present invention, a method for forming the optical modulator, and a method for controlling the optical modulator are also provided.
