在ZnSe中，与氟原子结合的激子具有几种量子光学应用的潜力。例子包括用于量子信息处理和无反转激光的光学可访问量子存储器。这些应用要求束缚激子跃迁耦合到具有高协同因子的腔中，这导致了低阈值激光的实验观察。我们报道了在3和6微米的微盘腔中掺氟的ZnSe量子威尔斯的激光。光致发光和选择性光致发光光谱证实了激光是由于束缚激子跃迁。
Excitons bound to flourine atoms in ZnSe have the potential for several quantum optical applications. Examples include optically accessible quantum memories for quantum information processing and lasing without inversion. These applications require the bound-exciton transitions to be coupled to cavities with high cooperativity factors, which results in the experimental observation of low-threshold lasing. We report such lasing from fluorine-doped ZnSe quantum wells in 3 and 6 micron microdisk cavities. Photoluminescence and selective photoluminescence spectroscopy confirm that the lasing is due to bound-exciton transitions.
