Abstract
The line broadening of intersubband transitions in In0.53Ga0.47As/In0. 52Al0.48As quantum wells is analysed within the microscopic pseudopote ntial approach, that implicitly takes all the band structure effects i nto account. Linewidths considerably broader than those in the convent ional GaAs/AlxGa1-xAs quantum wells are found, indicating that these n ew type of quantum wells should be advantageous only when larger trans ition energies are necessary.
