Abstract :
Mid-infrared intersubband electroluminescence is reported in InAs single quantum wells embedded in InAs/AlSb quantum cascade structures. The observed emission energy is in good agreement with calculations based on the multiband k·p theory. The dominant polarisation of the emitted light is perpendicular to the quantum well layers.
