Abstract

A terahertz device includes a first waveguide, which is a plasmonic waveguide, having a first core with a nonlinear material, such as a ferroelectric material, and having a cladding with a first cladding portion including, at a first interface with the first core, a first cladding material that is an electrically conductive material. The terahertz device can include an antenna having a first and a second arm (for receiving or for emitting or for both, receiving and emitting electromagnetic waves in the terahertz range); a first and a second electrode arranged close to the first waveguide.
