摘要

我们最近证明了理想的量子线发射可以在垂直腔面发射激光器(VCSEL)类结构中实现，其中，在圆柱形VCSEL的有源多量子阱(QW)平面的外围区域有效地形成三维瑞利低语通道模式的甜甜圈形状微腔，使光子量子环(PQR)发射流形由于量子圈效应和激光捕获载流子有序现象自然产生。环面变成黑色(几乎完美反射)的瑞利PQR激光画廊，具有异常的量子线特性，如微安范围的阈值电流和根号t相关的红移。根据无中心VCSEL区域的空心型PQR器件的行为，发现PQR的异常性质与VCSEL无关。

Photonic quantum ring emission of 3D Rayleigh's cavity

We have recently demonstrated that ideal quantum wire emissions can be achieved in a vertical cavity surface emitting laser (VCSEL)-like structure, where a donut-shape microcavity of three-dimensional Rayleigh's whispering gallery modes is effectively formed in the peripheral region of the active multi-quantum-well (QW) planes of the cylindrical VCSEL so that photonic quantum ring (PQR) emission manifolds naturally emerge due to the quantum corral effect and laser-trapped carrier ordering phenomena. The toroid becomes black (nearly perfect reflection) Rayleigh's gallery of the PQR laser, with anomalous quantum wire properties, such as microampere-range threshold currents and square-root-T dependent redshifts. The anomalous PQR properties are also found to be independent of the VCSEL according to the behaviors of the hollow-type PQR devices without the central VCSEL region.
