A new optical switch is described which uses a dense 2DEG (two-dimensional electron gas) as the bottom side of a waveguide. Modulating the reflectivity of the electron gas modulates the light output. This can be done either electronically or optically. Predictions are made about the feasibility of devices in III-V technology for 10.6 μm wavelength. Ps switching and low power dissipation are expected.
