We have used interband photoluminescence (PL) spectroscopy to demonstrate the occurrence of an intersubband population inversion in a ${\mathrm{G}\mathrm{a}\mathrm{A}\mathrm{s}/\mathrm{A}\mathrm{l}}_{x}{\mathrm{Ga}}_{1\ensuremath{-}x}\mathrm{As}$ tri

This letter reports the observation of intersubband electroluminescence from a single-period resonant tunneling structure. Intersubband emission (λ≈8.4 μm), with a full width at half maximum of 7 meV, was observed from a GaAs/AlGaAs triple barrie

We report the observation by photoluminescence (PL) spectroscopy of cross‐barrier recombination between spatially separated two‐dimensional electron and hole gases confined respectively in the quantum well (QW) and collector accumulation layer of

The authors report the first observation of intersubband electroluminescence in GaAs/AlGaAs-based quantum cascade structures. A 100 A Al0.15Ga0.85As/Al0.4Ga0.6As well is employed to bridge the individual active regions to enhance the overall quantum

We report the results of interband photoluminescence experiments on a series of GaAs/AlGaAs triple barrier tunnelling structures containing asymmetric coupled quantum wells. These experiments allow the relative populations of the n =1 (E1) and n =2 (
