Abstract :
A new optical switch is described which uses a dense 2DEG (two-dimensional electron gas) as the bottom side of a wave guide. 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 mu m wavelength. Ps switching and low power dissipation are expected.
