Abstract

Interwell carrier distribution is a process of major importance for the operation of multiple quantum well (MQW) lasers. For a laser to operate effectively, a uniform carrier distribution in all the wells is needed. However, previous studies have shown that for both, cw and pulsed current injection, carrier densities in different wells are not equal. The main reason for such effect is a slow interwell hole transport.
