Abstract: Picosecond time-resolved streak-scope measurements of the electroluminescence (EL) of AlAs/GaAs double-barrier resonant tunneling light-emitting diodes are presented The samples are excited by fast electrical pulses (250 ps rise and fall times) and both quantum well and bull; GaAs emissions are monitored, at room and liquid nitrogen temperatures. The effects of barrier thickness, temperature, voltage and device size and geometry on the switching speed are investigated. The optical response of the diodes is very fast (down to 200 ps), showing no significant dependence on temperature and barrier thickness.
