Abstract :
A report is made of the pulsed operation of In/sub 0.53/Ga/sub 0.47/As-AlAs/sub 0.56/Sb/sub 0.44/ quantum cascade structures on an InP substrate. The very large conduction band offset (~1.6 eV) of this material system made it possible to observe electroluminescence at (lambda)~3.1 (mu)m, the shortest emission wavelength yet observed for any intersubband device.
