提出并分析了一种利用半导体量子威尔斯阱中强电子自旋相干性实现电磁感应透明的新方案。该方案利用量子阱波导中的光空穴跃迁，在没有外磁场的情况下诱导电子自旋相干。对于特定的偏振态，光洞跃迁形成交叉双V系统。在这个系统中的EIT强烈修改由电子自旋相干诱导的相干波混频过程。
We propose and analyze a novel scheme to realize electromagnetically induced transparency (EIT) via robust electron spin coherence in semiconductor quantum wells. This scheme uses light hole transitions in a quantum well waveguide to induce electron spin coherence in the absence of an external magnetic field. For certain polarization configurations, the light hole transitions form a crossed double-V system. EIT in this system is strongly modified by a coherent wave mixing process induced by the electron spin coherence.
