在一个具有三能级V 型能级结构的耦合半导体双量子阱中，研究了相干调控下光学双稳态以及双稳态与多稳态的转化行为。研究结果表明，在此物理模型下，光学双稳态的阈值强烈依赖于系统中的非相干抽运强度和存在自发辐射相干下的相对相位，同时，通过调制相位大小，可使系统出现光学双稳态和多稳态之间的相互转换。

Conversion behavior of optical bistability and optical bistability/multistability in coupled semiconductor double quantum wells with the structure of V-type is investigated. It is shown that the threshold of optical bistability strongly depends on intensity of incoherent pump field and relative phase under the condition of existence of spontaneous radiation coherence. Moreover, conversion between optical bistability and multistability can be easily achieved just by the phase modulation.
