Abstract
An optical switching device is comprised of an asymmetrical double barrier resonant tunnelling diode (RTD) connected in series with load resistance apparatus to a power source, apparatus for illuminating the RTD with an infrared incident light beam, apparatus for applying signal power to the RTD, and apparatus for varying the power within the RTD.
