Abstract

Feasibility of a new integrated waveguide amplitude modulator/switch in the visible and JR spectrum, based on the absorption of light due to the linear interaction of the incident laser and a two-dimensional plasma layer is demonstrated. Plasma layers are generated via the Muller effect at the waveguide's interfaces. Carrier mobility is increased in the interfaces by inserting a few monolayers of a high-mobility material in the interface. A plasma wave is excited in the two-dimensional gas, when it is illuminated by electromagnetic radiation. Thus, due to the energy transfer from the electromagnetic wave to the plasma wave, the output light intensity can be controlled.
