Abstract
In this paper we discuss inter-conduction band gain without global inversion by engineering the conduction band effective masses. We recover the expected dispersive gain shape for similar masses and contrasting results if the effective masses characterizing the relevant subbands are very different. The relevance of many-body effects is investigated and numerical results are present for different structures.
