| 英文摘要 | The RT regions of an ISB light emitter comprise pre-biased SLs and a multiplicity of split quantum wells (SPQWs). A SPQW is a quantum well that is divided into a multiplicity of sub-wells by a first barrier layer sufficiently thin that the upper and lower energy states are split beyond their natural broadening and contribute to different minibands in each RT region. In contrast, adjacent SPQWs are coupled to one another by second barrier layers. The thicknesses of the latter layers are chosen so that minibands are created across each RT region. In one embodiment, the emitter includes an I/R region between adjacent RT regions, and in another embodiment the I/R regions are omitted. |
