Abstract
An optical modulation technique has been used to observe the electromo dulation of photoluminescence in single and multiple quantum wells. It is shown that this photomodulated photoluminescence technique can yie ld similar information to that obtained from electroabsorption and pho toabsorption experiments but, because it does not require special samp le geometry or sample preparation, it is easier to implement, especial ly in the case of samples grown on nontransparent substrates.
