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.
其他摘要	ISB光发射器的RT区域包括预偏置SL和多个分裂量子阱（SPQW）。 SPQW是量子阱，其通过足够薄的第一势垒层被分成多个子阱，使得上和下能态被分裂超过它们的自然扩展并且有助于每个RT区域中的不同微带。相反，相邻的SPQW通过第二势垒层彼此耦合。选择后面的层的厚度，使得在每个RT区域上产生微带。在一个实施例中，发射极包括在相邻的RT区之间的I / R区，在另一个实施例中，I / R区被省略。
