Abstract :
The electrical and optical characteristics of a bistable resonant tunnelling light emitting diode are reported. The maximum frequency of operation is determined by electron tunnelling escape rather than by radiative recombination. Switching time constants of less than 200 ps are measured, limited by the duration of the electrical excitation.
