量子阱微管环形谐振腔中的三阶受限光模
Three-Dimensionally Confined Optical Modes in Quantum Well Microtube Ring Resonators
摘要：
我们报告的微管环形谐振器与量子阱嵌入作为一种光学活性材料。在很宽的能量范围内观察到光学模式。它们的性质强烈地依赖于微管沿其轴线的精确几何形状。特别是，我们观察到（i）优先发射的光的内边缘的微管和（ii）光的限制也在管轴的方向上由一个轴向变化的几何形状，这是解释在一个扩展的波导模型。
英文摘要：
We report on microtube ring resonators with quantum wells embedded as an optically active material. Optical modes are observed over a broad energy range. Their properties strongly depend on the exact geometry of the microtube along its axis. In particular we observe (i) preferential emission of light on the inside edge of the microtube and (ii) confinement of light also in direction of the tube axis by an axially varying geometry which is explained in an expanded waveguide model.
